Heavy quark decays and CKM

Parallel session

We have conducted an investigation and prediction of the angular observables in the complete 4-body angular distribution for the decay of $\Lambda_b^0 \to \Lambda_c^{+}(\to \Lambda \pi^{+})\tau \bar{\nu_{\tau}}$. This analysis takes into account all New Physics (NP) operators in a model-independent manner while analyzing the NP sensitivity of each angular observable with the associated NP...

Exotic quarkonium-like states

Parallel session

The speaker will discuss the new structures reported by the CMS collaboration recently. Three structures are found in the J/ψJ/ψ mass spectrum in proton-proton collisions at 13 TeV, and a model with quantum interference among these structures provides a good description of the data. Among them, a new structure with mass around 6.6 GeV is observed with a local significance > 5 sigma. Another...

Exotic quarkonium-like states

Parallel session

The first observation of the concurrent production of two $\rm{J}/\psi$ mesons in proton-nucleus collisions will be presented. The analysis is based on a data sample recorded at a nucleon-nucleon center-of-mass energy of 8.16 TeV by the CMS experiment at the CERN LHC corresponding to an integrated luminosity of 174.6 $\rm{nb}^{-1}$. The $\rm{J}/\psi$ mesons are reconstructed in their...
