We present predictions for a variety of single-inclusive observables that stem from the production of charm and bottom quark pairs at the 7 TeV LHC. They are obtained within the FONLL semi-analytical framework, and with two "Monte Carlo + NLO" approaches, MC@NLO and POWHEG. Results are given for final states and acceptance cuts that are as close as possible to those used by experimental collaborations and, where feasible, are compared to LHC data.

“…Then, hadron momenta are sampled from Fragmentation Functions (FFs). The parametrization used in our work is taken from the literature [16,17], with the phenomenological parameters fitted to reproduce experimental data [14,18,19] The agreement between our results and the experimental data, on cc and bb production, provided by ALICE and CMS Collaborations in pp collisions at √ s = 2.76 and 7 TeV is fairly good [3].…”

Abstract. A multi-step setup for heavy-flavor studies in high-energy nucleus-nucleus (AA) collisions -addressing within a comprehensive framework the initial QQ production, the propagation in the hot medium until decoupling and the final hadronization and decays -is presented. The propagation of the heavy quarks in the medium is described in a framework provided by the relativistic Langevin equation and the corresponding numerical results are compared to experimental data from RHIC and the LHC. In particular, outcomes for the nuclear modification factor R AA and for the elliptic flow v 2 of D/B mesons, heavy-flavor electrons and non-prompt J/ψ's are displayed.

“…To describe these hadronization processes, from ref. [42] we employ the nonperturbative B-hadron FFs determined at NLO in the ZM-VFN scheme through a global fit to e + e − annihilation data taken by OPAL [43], ALEPH [44] and SLD [45,46]. In ref.…”

Light and heavy charged Higgs bosons are predicted by many models with an extended Higgs sector such as the two-Higgs-doublet model (2HDM). Searches for the charged Higgs bosons have been done by the ATLAS and the CMS experiments at the Large Hadron Collider (LHC) in proton-proton collision. However, a definitive search of charged Higgs bosons still has to be carried out by the LHC experiments. The experimental observation of charged Higgs bosons would indicate physics beyond the Standard Model. In the present work we study the O(α s ) correction to the energy spectrum of the inclusive bottom-flavored mesons (X b ) in polarized top quark decays into a light charged Higgs boson (m H + < m t ) and a massless bottom quark followed by the hadronization process b → X b in the type-I 2HDM, i.e. t(↑) → H + b → H + X b + Jet. This spin-dependent energy distribution is studied in two different helicity coordinate systems. This study could be considered as a new channel to indirect search for the charged Higgs bosons. To present our phenomenological predictions, we restrict ourselves to the constraints on the m H + − tan β parameter space determined by the recent results of the CMS and the ATLAS collaborations.
