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 ...

Use of Kefir in Cheese Ball Production: Physicochemical, Textural, Rheological, and Sensory Properties. [PDF]

open access: yesFood Sci Nutr
In this study, we produced cheese balls by mixing kefir with white cheese in different ratios (0%–25%–50%–75%–100%) to improve the consumption diversity of kefir, and the physicochemical, textural, rheological, and sensory properties of cheese ball samples were examined.

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.

Electroweak and finite width corrections to top quark decays into transverse and longitudinal $ W $-bosons [PDF]

open access: yes, 2002
We calculate the electroweak and finite width corrections to the decay of an unpolarized top quark into a bottom quark and a $ W $-gauge boson where the helicities of the $ W $ are specified as longitudinal, transverse-plus and transverse-minus. Together
