Intrinsic bottom and its impact on heavy new physics at the LHC

open access: yesEPJ Web of Conferences, 2016
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 ...

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 ...

Search for a charged Higgs boson decaying into top and bottom quarks in events with electrons or muons in proton-proton collisions at s $$ \sqrt{\mathrm{s}} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2020
A search is presented for a charged Higgs boson heavier than the top quark, produced in association with a top quark, or with a top and a bottom quark, and decaying into a top-bottom quark-antiquark pair.

Search for a charged Higgs boson decaying to charm and bottom quarks in proton-proton collisions at s = 8 $$ \sqrt{s}=8 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search for charged Higgs boson decaying to a charm and a bottom quark ( H + → c b ¯ $$ {\mathrm{H}}^{+}\to \mathrm{c}\overline{\mathrm{b}} $$ ) is performed using 19.7 fb−1 of pp collision data at s = 8 $$ \sqrt{s}=8 $$ TeV.

Bottom-quark effects in Higgs production at intermediate transverse momentum

open access: yesJournal of High Energy Physics, 2018
We provide a precise description of the Higgs boson transverse momentum distribution including top and bottom quark contributions, that is valid for transverse momenta in the range m b  ≲ p ⊥ ≲ m t , where m b and m t are the bottom and top quark masses.

Analytic decay width of the Higgs boson to massive bottom quarks at next-to-next-to-leading order in QCD

open access: yesJournal of High Energy Physics
The Higgs boson decay to a massive bottom quark pair provides the dominant contribution to the Higgs boson width. We present an exact result for such a decay induced by the bottom quark Yukawa coupling with next-to-next-to-leading order (NNLO) QCD ...
