Measurement of nonprompt and prompt D0 azimuthal anisotropy in Pb-Pb collisions at √SNN = 5.02 TeV [PDF]

open access: yesEPJ Web of Conferences, 2023
Heavy quarks are primarily produced via initial hard scatterings, and thus carry information about the early stages of the Quark-Gluon Plasma (QGP). Measurements of the azimuthal anisotropy of the final-state heavy flavor hadrons provide information ...

Quarkonium production in pp and heavy-ion collisions [PDF]

open access: yesEPJ Web of Conferences
Campus Frankfurt, 60438 Frankfurt, Germany Abstract. We describe quarkonium production in pp and heavy-ion collisions by using the Remler’s formalism where quarkonium density operator is applied to all possible combination of heavy quark and heavy ...

Weak decays of bottom-charm baryons: $$\mathcal {B}_{bc}\rightarrow \mathcal {B}_bP$$ B bc → B b P

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
After the discovery of the double-charm baryon $$\Xi _{cc}^{++}$$ Ξ cc + + by LHCb, one of the most important topics is to search for the bottom-charm baryons which contain a b quark, a c quark and a light quark.

On the intrinsic bottom content of the nucleon and its impact on heavy new physics at the LHC [PDF]

open access: yes, 2015
Heavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most analyses rely on the assumption that the charm and bottom PDFs are generated perturbatively by gluon splitting and do not ...

Higgs production in bottom quark fusion: matching the 4- and 5-flavour schemes to third order in the strong coupling

open access: yesJournal of High Energy Physics, 2020
We present analytic results for the partonic cross sections for the production of a Higgs boson via the fusion of two bottom quarks at N3LO in QCD perturbation theory in the five-flavour scheme.

Search for the signal of vector-like bottom quark at LHeC in the final state with 3 b-jets

open access: yesNuclear Physics B, 2023
Vector-like quarks arise in many new theories beyond the Standard Model, which is driven by several theoretical issues. In a framework of the Standard Model simply extended by an SU(2) singlet vector-like bottom quark, we present a study of single ...

Search for a singly produced third-generation scalar leptoquark decaying to a τ lepton and a bottom quark in proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search is presented for a singly produced third-generation scalar leptoquark decaying to a τ lepton and a bottom quark. Associated production of a leptoquark and a τ lepton is considered, leading to a final state with a bottom quark and two τ leptons ...

Completing 1/ m b 3 $$ {m}_b^3 $$ corrections to non-leptonic bottom-to-up-quark decays

open access: yesJournal of High Energy Physics, 2021
We compute the contributions of dimension six two-quark operators to the non-leptonic decay width of heavy hadrons due to the flavor changing bottom-to-up-quark transition in the heavy quark expansion.

Next-to-leading-order QCD corrections to Higgs production in association with a jet

open access: yesPhysics Letters B, 2023
We compute the next-to-leading-order (NLO) QCD corrections to the Higgs pT distribution in Higgs production in association with a jet via gluon fusion at the LHC, with exact dependence on the mass of the quark circulating in the heavy-quark loops.

On the light massive flavor dependence of the large order asymptotic behavior and the ambiguity of the pole mass

open access: yesJournal of High Energy Physics, 2017
We provide a systematic renormalization group formalism for the mass effects in the relation of the pole mass m Q pole and short-distance masses such as the M S ¯ $$ \overline{\mathrm{MS}} $$ mass m ¯ Q $$ {\overline{m}}_Q $$ of a heavy quark Q, coming ...
