Hadron spectroscopy and heavy-flavour physics

Talk

Recent measurements of tree-level $b\to c\ell\nu$ and loop-level $b\to s \ell^{+}\ell^{-}$ decays show an intriguing and consistent pattern of tensions between measured observables and Standard Model predictions. These tensions are referred to collectively as the flavour anomalies. This talk outlines the current experimental status of the flavour anomalies, with particular focus on...

173. The interpretation and prospects of the B meson anomalies

Hadron spectroscopy and heavy-flavour physics

Talk

B anomalies attract a lot of attention in the last few years. The charged current caused ratios of the taounic semileptonic B decays to D() and the muonic one indicate deviations from the standard model prediction. In the case of flavor changing neutral current processes ratio of muonic and electronic in B to K() transitions and similar transitions of b to s l+ l- in various decays again,...

111. Belle II experiment: status and prospects

Hadron spectroscopy and heavy-flavour physics

Talk

The Belle II experiment at the SuperKEKB energy-asymmetric e+e− collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The target luminosity of the machine is $6\times10^{35}$ cm$^{−2}$s$^{−1}$ and the Belle II experiment aims to record 50 ab$^{−1}$ of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the...

Hadron spectroscopy and heavy-flavour physics

Talk

In scattering experiments, a multitude of hadronic states was observed
already in the 50s and 60s of the last century. In order to explain
their abundance, a systematic approach was taken to search for an
underlying structure. Quantum chromodynamics was developed as a
theoretical description of these strongly interacting particles,
explaining the interactions between quarks and gluons, of...

109. Hadron Spectroscopy from Lattice QCD

Jozef Dudek

Hadron spectroscopy and heavy-flavour physics

Talk

I will describe how the discrete spectrum of eigenstates of QCD in a finite box, calculated using lattice QCD techniques, can be used to infer hadron-hadron scattering amplitudes. I will illustrate the approach with the results of several calculations of coupled-channel meson-meson scattering, commenting upon the resonant content.

162. Measurements of heavy-flavor production as a function of multiplicity with ALICE at the LHC

Hadron spectroscopy and heavy-flavour physics

Talk

Heavy quarks (charm and beauty) are produced at the initial stages of the relativistic hadronic collisions in hard scattering processes. The study of heavy-flavor production provides a stringent test to perturbative Quantum Chromo-Dynamics (pQCD) calculations in proton-proton (pp) collisions and can help in disentangling cold nuclear matter (CNM) effects in proton-lead (p--Pb) collisions....
