The first experimental results from pPb collisions at 5 TeV on the particle yields and azimuthal anisotropies as function of transverse momentum show a very similar behavior in comparison to the observations in heavy-ion collisions, where the quark-gluon plasma (QGP) can be produced. Such pPb results have indeed been explained in the framework of models including a QGP phase such as EPOS3. Heavy-f

Motivated by previous works in which the $\rho B^{\ast}$ and the $B^{\ast} \bar{B}^{\ast}$ interactions were studied, we calculate the interaction of the three-body system $\rho B^{\ast} \bar{B}^{\ast}$. We know that the $\rho B^{\ast}$ interaction in $J=2$ is stronger than in any other possible spin, and also an attractive interaction was found in the $B^{\ast} \bar{B}^{\ast}$ system, producing i

We investigate the central exclusive production of $\rho\rho$ pairs in $pp$ collisions at LHC energies. At low central invariant mass this process can be considered as a possible nonresonant background for glueball searches in four-body final states. Above the resonance region nonperturbative production mechanism can be studied. All calculations have been performed using generator GENEX(arXiv:1411

Investigation of three-nucleon systems is important for testing nuclear potentials. Quantitatively, it can be done by comparing observables calculated with the use of Faddeev equations with the results of precise measurements. Modern realistic nucleon-nucleon (NN) potentials describe well two nucleon systems. They are successfully applied to predict observables of deuteron-proton breakup reaction

It is known that the lifetime of relativistic particles depends on their energy. For example, the lifetime of muons in cosmic rays increases to $\gamma=(1-\beta^2)^{-1/2}$ times. Based on uncertainty principle, for the short-lived particles the lifetime is determined from the full width ($\Gamma=\hbar/\tau$) of energy distribution of the decaying particles. Currently the dependence of the lifetime

In this talk we will discuss two important processes of the low-energy hadron physics: the rare decay $\pi^0\to e^+ e^-$ and the Dalitz decay of $\pi^0$.
We briefly summarize experimental and theoretical results on the decay $\pi^0\to e^+e^−$. The analytical two-loop QED corrections together with the bremsstrahlung contribution beyond the soft-photon approximation are reviewed.
Finally, we

There are still discrepancies between theory and experimental data in the polarisation observables of $dp \to ppn$ reaction in the low and intermediate energies, despite of significant process in the development of theoretical models which include three and more nucleon forces and relativistic effects. The data of $dp \to ppn$ reaction have been accumulated at 300, 400 and 500 MeV in the Nuclotron

An experiment to investigate the $^1$H$(d,pp)n$ breakup reaction using a deuteron beam of 340, 380 and 400 MeV and the WASA detector has been performed at the Cooler Synchrotron COSY Julich. The studied energy region, below but close to a pion production threshold, may provide information on various aspects of nuclear interactions, in particular on relativistic eff ects and their interplay with t

We'll discuss the relation between Reggeons and resonances. Based on analyticity (dispersion relations), one can formalize this relation into a mathematical statement relating the resonance region to the high energy (Regge) region.
One can then use these sum rules to constraints the extraction of resonances from the high energy data.
We will illustrate this technique on various processes (Pi-N

The unambiguous identification of hadron modifications in hot and dense QCD matter is one of the important goals in nuclear physics. In the regime of 1 - 2 GeV kinetic energy per nucleon, HADES has measured rare and penetrating probes in elementary and heavy-ion collisions. The dominating constituents of the matter formed in the collision zone are primordial nucleons. The main creation mechanism o

A large set of high precision data of $^1H(\vec{d},p p)n$ reaction at beam energy of 130 MeV were collected with SALAD and GeWall detectors. The polarized deuteron beams were
produced with the use of the ion sources of the AGOR (KVI Groningen, The Netherlands) and COSY (IKP FZ-Juelich, Germany) accelerators, respectively.
The $\vec{d}p$ breakup reaction is one of the simplest processes to stud

J-PET detector has been recently constructed at the Jagiellonian University. It is optimized for the measurement of momentum and polarization of photons from the electron-positron annihilations. It is built out of strips of organic scintillator, forming a cylinder. Light signals from each strip are converted to electrical signals by photomultipliers placed at opposite ends of the strip. The signa

We calculate the pole mass and width of the $\Delta$ resonance to the third order in chiral effective field theory. We choose the complex-mass renormalization scheme in our calculation and compare the convergence behavior of both the complex-mass scheme (CMS) and the small-scale expansion (SSE) calculating the loop contributions to the delta resonance mass. Contributions of the renormalized loop d

The interaction between $\eta$ mesons and hadrons is an intensively investigated topic. Due to its stength it might lead
to the formation of $\eta$-mesic nuclei. In order to study the characteristics of this interaction a measurement of the reaction
$p+d\rightarrow d+\eta+p_{sp}$ has been performed at the ANKE spectrometer at the COSY accelerator of the Forschungszentrum Juelich. In this context

The antinucleon-nuclei annihilation cross section $\sigma_{ann}$ at very low energy has been measured at the LEAR facility (CERN) during the 80's and 90's and recently at the Antiproton Decelerator.
The antineutron data at momenta below 180 MeV/c on several nuclei showed a steep rise which is expected only for the antiproton projectile due to its negative charge.
The difference between the anti

We analyze the second-class current decays $\tau^-\to\pi^-\eta(')\nu_\tau$ in the framework of Chiral Perturbation Theory with Resonances. Taking into account $\pi^0-\eta-\eta'$ mixing, the $\pi-\eta(')$ vector form factor is extracted, in a model-independent way, using existing data on the $\pi-\pi_0$ one. For the participant scalar form factor, we have considered different parameterizations orde

The existence of $\eta$-mesic nuclei in which the $\eta$ meson is bound with nucleus with the strong interaction was postulated by Haider and Liu already in 1986, however till now no experiment confirmed it empirically. Recent theoretical studies of hadronic- and photoproduction of $\eta$ meson, revealing posibility of existence for $\eta$-mesic bound states for light nuclei like $^3$He, give the

A wide range of fundamental effects in the hadronic sector can be investigated only by means of controlling the spin degrees of freedom. Even though polarized beams of protons are routinely produced, preparation of polarized antiproton beam still poses a formidable challenge [1].
The way to achieve it would be relatively easy if some polarization is created during the antiprotons production. Fo

The $\eta$ meson production process was studied via measurements of the analyzing power, $A_{y}$ for the $\vec{p}p\to pp\eta$ reaction. The measurement was performed with the WASA-at-COSY detector at excess energies of 15 MeV and 72 MeV. The missing mass and invariant mass techniques were used to identify $\eta$ meson. The angular distribution of the analyzing power of for the $\eta$ meson was det

In this talk we present a new parametrization of the hadronic current for the decay $\tau \to \pi \pi \pi \nu_\tau$ derived from the chiral lagrangian with explicit inclusion of resonances. We have included both scalar, vector and axial-vector resonances as well, for the first time, the lowest tensor resonance (f2(1270)). Both single and double-resonance contributions to the hadronic form factors

In this work we study the $\rho(\omega)B^{\ast}$ interaction using the local
Hidden Gauge approach and a non-perturbative method. We search for poles
in the T-matrix formalism, solving the factorized Bethe-Salpeter
equation in coupled channels and identifying the different states as $\rho
B^{\ast}$ bound states for all the possible spins, $J=0,1,2$. We fit the
parameters of the theory in orde

The BES data on the $J/\psi \to \eta K^{\star 0} \bar{K}^{\star0}$ reaction show a clear enhancement in the $K^{\star 0} \bar{K}^{\star 0}$ mass distribution close to the threshold of this channel. Such an enhancement is usually a signature of a L=0 resonance around threshold, which in this case would correspond to an $h_1$ state with quantum numbers $I^G(J^{PC})=0^-(1^{+-})$. A state around 1800

We investigate the presence of thermodynamic instabilities in a hot and dense nuclear medium where a phase transition from a gas of massive hadrons to a nearly massless baryon, antibaryon plasma can take place. The analysis is performed by requiring the global conservation of baryon number and zero net strangeness in the framework of an effective relativistic mean field theory with the inclusion o

A review of familiar results of the three-point Green functions of currents in the odd-intrinsic parity sector of QCD is presented. Such Green functions include very well-known examples of $VVP, VAS$ or $AAP$ correlators. We also present new results for $VVA$ and $AAA$ Green functions that have not yet been studied extensively in the literature before, more importantly with a phenomenological stud
