            Whether a Kaonic bound system, $K^-pp$, exists or not is one of important issues in Strangeness nuclear physics at J-PARC. Based on low-energy $KN$ scattering data and kaonic-atom X-ray data, it is well known that the $KN$ interaction near threshold has a strong attraction in the isospin 0 channel. It can be a driving force to form the Kaonic bound state, $K^-pp$. The FINUDA and DISTO collaboratio

            Since many years the strong final state interaction between eta mesons and light nuclei and the discussed possibility for the formation of $\eta$-mesic nuclei has attracted broad experimental and theoretical investigations. Prominent examples are production experiments on the $^3{He$-\eta$ final state which present an unexpected strong total cross section enhancement at threshold, indicating the p

            Recent studies of kaonic atoms, few-body kaonic quasibound states and kaonic 
nuclei based on s-wave ${\bar K}N$ chiral interaction models that are consistent 
with the SIDDHARTA $K^-$ hydrogen data are reviewed, focusing on the $K^-pp$  
dibaryon. Remarks are made on low-lying dibaryons other than $\Lambda(1405)N$, 
particularly those involving p-wave interactions of pions with octet baryons.

Surprisingly, in a certain setup the tiny difference between a world of matter and a world of antimatter, the famous violation of the CP symmetry (C -- charge conjugation; P -- parity), becomes responsible for the possibility of reveali

            The $\Lambda^*$=$\Lambda (1405)$ plays an essential role in forming anti-kaonic nuclear clusters, the simplest one of which is $K^-pp=(K^-p)-p=\Lambda^*-p$. In relation to this clustering structure we have examined the reaction processes, $^3$He$(K^-,n)K^-pp$ and D$(\pi^+,K^+)K^-pp$, of the recent E15 and E27 J-PARC experiments.

            The cosmological standard model assumes that a large fraction of the universe is made of dark matter while only a small fraction of matter is made of ordinary baryonic matter. Up to now, the nature of dark matter is unknown, and this is certainly one of the most pressing puzzles of today's physics. Dark matter interacts in cosmology only via gravitation with ordinary matter. In particle physics, h

            Since the 1950's people search for permanent Electric Dipole Moments (EDM) of fundamental systems, as a non-zero EDM would be an unambiguous manifestation of parity (P) and time reversal symmetry (T) violation. Assuming conservation of CPT, T violation in a fundamental system also means CP violation. EDMs are considered promising candidate systems, as this turns out to be a natural consequence of

            The long history of dibaryon searches dating back to the fifties has been a very changeful one - with many ups and downs. After Gell-Mann's famous paper on the quark model Dyson and Xuong were the first to correlate this topic with SU(6) and six quark systems -- still in the year 1964. But it was not until Jaffe's note in 1977 about a bound $\Lambda \Lambda$ system, the H-dibaryon, when a real rus

            The BES data on the $J/\psi\to\etaK*^0\bar{K}*^0$ reaction show a clear enhancement in the $K*^0\bar{K}*^0$ 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 h1 state with quantum numbers $I^G(J^{PC})=0^-(1^{+−})$. A state around 1800 MeV results from the interaction

            Recent results from the Belle experiment will be presented, using the full data sample of Belle, corresponding to 772 million $B\bar{B}$ pairs. Special emphasis is given to precise measurements on $CP$ violation and tests of $CPT$ invariance. The presentation will also include new data on $T$ violation and complementary measurements from other world data.

            We discuss production of charmed mesons in proton-proton collisions at the LHC. The cross section for inclusive production of $c \bar c$ pairs is calculated in the framework of the $k_{\perp}$-factorization approach, i.e. effectively includes next-to-leading order corrections. Taking wide range of $x$ values necessary for the calculation we use and test several unintegrated gluon distributions fro

            Strange mesons are the rare probes of the nucleus-nucleus collisions investigated by the FOPI collaboration at the beam kinetic energy range of 1-2A GeV. This energy falls below ($K^-$, $\phi$(1020) ) or near ($K^+$, $K^0$) thresholds in the free nucleon-nucleon collision, therefore a considerable contribution to the production of these particles is expected to proceed via the secondary channels,

            Spectroscopy of deeply-bound pionic atoms using the (d,$^3$He) reaction has been shown to be a powerful tool to study the pion in-medium modification. The 1s binding energies of medium-heavy pionic atoms can be related to the "partial restoration" of chiral condensate with the Tomozawa-Weinberg and the Gell-Mann-Oakes-Renner relations, as was demonstrated in our previous experiment carried out at

            The anomalous magnetic moment of the muon $(g-2)_\mu$ is one of the most precisely measured quantities in particle physics (0.54~ppm). There is a long-standing discrepancy of 3-4 standard deviations between the direct measurement of $(g-2)_\mu$ and its theoretical evaluation. This theoretical prediction is subdivided into three contributions: QED, weak and hadronic.
The QED and weak parts can be

            COMPASS is a multi-purpose fixed-target experiment at the CERN Super Proton Synchrotron aimed at studying the structure and spectrum of hadrons. One main goal is the search for new hadronic states, in particular hybrid mesons and glueballs. Its large acceptance, high resolution, and high-rate capability make the COMPASS experiment an excellent device to study the spectrum of light-quark mesons in

            The primary focus of the Qweak experiment at Jefferson Lab is to perform a precision measurement of the proton’s neutral weak charge. The Standard Model gives a firm prediction for the weak charge; any deviation from that can be interpreted as evidence for new physics beyond the Standard Model. The experiment measures the parity-violating asymmetry in the elastic scattering of 1.1 GeV longitudin

            Recent developments and phenomena related to low-energy antikaon interactions with baryonic systems are summarized. Expectations for kaonic deuterium and for the $\bar{K}$-deuteron scattering length are outlined in view of planned experiments. Updated information is provided concerning the structure of the $\Lambda(1405)$. The quest for kaon condensation and the role of strangeness in dense baryon
