Heavy charmonia and bottomonia in a deconfined quark-gluon plasma are studied by considering the $B_c$ family of mesons. With the introduction of this bound state of a charm and a beauty quark at finite temperature the behavior of the quarkonium is investigated in an energy region between the $\psi$ and the $\Upsilon$ states. Calculations are performed within a potential model.

A quasi two-body QCD factorization is used to study the $D^0 \rightarrow K^0_S \pi^+ \pi^-$ decay channel. Starting from the weak effective Hamiltonian, 28 tree and annihilation (W-exchange) amplitudes build up the full $D^0 \rightarrow K^0_S \pi^+ \pi^-$ amplitude [1]. The meson-meson final state interactions are described by the kaon-pion and pion scalar and vector form factors for the S and P w ... More

Exclusive production has been proposed as a unique environment in which to study vector meson photoproduction, as well as light meson production via Double-Pomeron exchange. In this talk we present CMS measurements of photon-induced and Central Exclusive Production from Run 1 of the LHC. The results, based on up to 5 fb$^{-1}$ of $pp$ collisions collected at $\sqrt{s}=7$ TeV, are compared to theor ... More

In this work we study the semileptonic decays of $\bar B_s$ mesons in the context of nonrelativistic constituent quark models. We estimate the uncertainties of our calculation using different interquark potentials to obtain the meson wave functions. We check the results from our model against the predictions of Heavy Quark Symmetry, in the limit of infinite heavy quark mass. We also study the nonl ... More
