This talk will be a review of recent developments in the evaluation of NLO QED predictions for the radiative ($\tau \rightarrow l \gamma \nu \bar \nu $) and the rare ($\tau \rightarrow l l l \nu \bar \nu$) tau decays, performed independently by two groups: Fael, Greub, Passera and Pruna, Signer, Ulrich. Fully differential NLO corrections are very important for the analysis of tau measurements...

There are still less than 50% of the hadronic decays of $J/\psi$
and $\psi(2S)$ known so far. We present an overview of the study of
the $J/\psi$ and $\psi(2S)$ production via ISR at BaBar. A few dozens of exclusive final states have been measured, many of them for the first
time. Excellent detector performance allows to measure the major decay modes with low systematic errors. We
present...

We will present inclusive method of the study of double charmed decays with strangeness $ B \to \bar{D}^{(*)}D_{s(J)}^{(*)} $. The study based on the missing mass distributions in inclusive transitions $ B \to \bar {D}^{(*)} X $, and thus in a way free from the assumptions about resonance decays $ D_{s(J)}^{(*)}$. We will also present the perspective of such studies on next generation Belle II...

Recent model-independent measurements of the absolute branching ratio of the normalization mode $\Lambda_c -> p^+ K^- \pi^+$ by the Belle$^1$ and BES3$^2$ collaborations have significantly increased the precision of previously measured decay channels. BES3 also independently updated the value for the $\Lambda^+_c \to\Sigma^+ \pi^- \pi^+$ mode, however the branching fraction into the...

Heavy quarks (charm and beauty) are produced in hard scattering processes at the early stage of the collision. Charmed-hadron production in small systems is important to test perturbative QCD calculations, to understand cold nuclear matter effects and to test possible collective effects. In addition their abundance is preserved during the subsequent collision stages making them effective...

In Pb-Pb collisions at the LHC, a hot and dense medium of deconfined quarks and gluons is formed (Quark-Gluon Plasma, QGP).
The QGP is conjectured to be the state of matter of the early Universe up to few microseconds after the Big Bang and may still exist in the core of neutron stars. One of the most striking signatures of the QGP formation in heavy-ion collisions is the suppression of jet...
