We consider the resummation of large logarithms in the distribution of the azimuthal angle between a Z boson and a jet produced in hadron-hadron collisions. The recombination shceme used in the reconstruction of the jets has a strong impact on the NLL resummation. Specifically when using the E-scheme (four-momentum addition of constituents of the jet), the resummation is highly non-trivial due...
The production of jets and photons at hadron colliders provides stringent tests of perturbative QCD. In this talk, results on fragmentation properties of jets containing B-hadrons will be presented. We present measurements of variables probing the properties of the event isotropies and measurements extremely sensitive to the strong coupling constant. The latest differential cross-section...
The ALICE experiment aims at investigating the properties of strongly-interacting matter in extreme conditions of temperature and energy density where the quark-gluon plasma (QGP) is formed. Heavy quarks (charm and beauty quarks), mostly produced via hard partonic scattering processes in the very early stage of the collisions, are efficient probes of the properties and dynamics of the QGP...
We discuss production of $D$ ($D^+, D^-, D^0, {\bar D}^0$) mesons in the proton proton collisions at the LHC (both collider mode and fixed target mode) in the framework of the BJM recombination model. We present rapidity and transverse momentum distributions of $D$ mesons and compare the recombination contribution to the dominant gluon-gluon fusion contribution and intrinsic charm...
