Observables involving heavy quarks can be computed in perturbative QCD in two different approximation schemes: either the quark mass dependence is fully retained, or it is retained only where needed to regulate the collinear singularity. The two schemes have different advantages and drawbacks. In particular, it is known that the structure of large logarithms arising from soft emissions is...
An overview of recent results on open heavy flavour production in small systems at the LHC will be presented. Comparisons with model calculations will be discussed.
The behaviour of quarkonia and open-heavy flavour hadrons in hadronic collisions provide a unique testing ground for understanding quantum chromodynamics (QCD). Although there has been significant progress, our understanding of hadronic collisions has been challenged by the observation of intriguing effects in high-multiplicity proton-proton and proton-Pb collisions, such as the discovery of...
Recent results on conventional spectroscopy were presented, including results from ATLAS, CMS and LHCb experiments at LHC. The new results on the measurement of excited heavy baryons properties ($\Xi_c^-$, $\Xi_b^0$) and searches for new doubly heavy states ($\Xi_{bc}$), measurements of the branching fractions of $B_c^+$ meson are presented.
