Parallel Session A2: Heavy quarks and symmetries
- Marc Pelizaeus (Ruhr University Bochum)
Charmless $B$ decays provide a unique portion of the Belle II program. The expected large signal yields with moderate backgrounds associated with efficient reconstruction of neutral particles enable world-leading determination of the CKM phase $\alpha/\phi_2$, a conclusive understanding of the so-called K-$\pi$ CP puzzle, and further insight into the nature of localized CP violation in...
We discuss the role of intrinsic charm (IC) in the nucleon for forward production of open charm meson in proton-proton collisions at low and high energies. The calculations are performed in collinear-factorization approach with on-shell partons, $𝑘_{T}$-factorization approach with off-shell partons as well as in a hybrid approach using collinear charm distributions and unintegrated (transverse...
In this talk, we will present the results of a coupled-channel analysis of the $J/\Psi p$ invariant mass distribution, in which the $P_c$ states are treated as $\Sigma_c^{(*)}\bar D^{(*)}$ molecules, [Phys. Rev. Lett., 124, 072001 (2020)] and its recent update [arXiv:2102.07159 [hep-ph]]. The effective $\bar D^{(*)}\Sigma_c^{(*)}$ meson-baryon scattering potential involves the long-range ...
First studies of discrete symmetries in purely leptonic systems started several decades ago and led to the discovery of weak interactions. Nowadays a positronium is considered as a fine probe into this subject, due to the fact that it is the lightest matter-antimatter system and at the same time an eigenstate of the C and P operators.
The Jagiellonian Positron Emission Tomography (J-PET)...
