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 ...

Z boson production in bottom-quark fusion: a study of b-mass effects beyond leading order [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We compute the total cross-section for Z boson production in bottom-quark fusion, applying to this case the method we previously used for Higgs production in bottom fusion.

The bottom-quark mass from non-relativistic sum rules at NNNLO [PDF]

open access: goldNuclear Physics B, 2015
We determine the mass of the bottom quark from high moments of the bb¯ production cross section in e+e− annihilation, which are dominated by the threshold region.

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.

Quark production in the bottom-up thermalization

open access: diamondPhysics Letters B
We investigate the impact of quark production on bottom-up thermalization in heavy-ion collisions. First, we extend the parametric estimates of bottom-up thermalization in pure gluon systems by incorporating quark production in the weak-coupling (high ...

Differential decay rates of CP-even and CP-odd Higgs bosons to top and bottom quarks at NNLO QCD

open access: yesJournal of High Energy Physics, 2018
We consider the decay of a neutral Higgs boson of arbitrary CP nature to a massive quark antiquark pair at next-to-next-to-leading order in perturbative QCD. Our analysis is made at the differential level using the antenna subtraction framework. We apply

Higgs boson production in association with massive bottom quarks at NNLO+PS [PDF]

open access: greenJournal of High Energy Physics
We study the production of a Higgs boson in association with a bottom-quark pair b b ¯ H $$ \left(b\overline{b}H\right) $$ at hadron colliders. Our calculation is performed in the four-flavour scheme with massive bottom quarks.

Bottom (70,1-) baryon multiplet [PDF]

open access: yesE3S Web of Conferences, 2020
The aim of this paper is to derive systems of equations for the amplitudes for the case of negative parity (70,1-) bottom nonstrange baryons and to calculate the masses of these particles. In order to calculate masses of (70,1-) bottom baryons we use the

Search for W′ bosons decaying to a top and a bottom quark at s=13TeV in the hadronic final state

open access: yesPhysics Letters B, 2021
A search is performed for W′ bosons decaying to a top and a bottom quark in the all-hadronic final state, in proton-proton collisions at a center-of-mass energy of 13TeV.

Improved indirect limits on charm and bottom quark EDMs

open access: yesJournal of High Energy Physics, 2022
We derive indirect limits on the charm and bottom quark electric dipole moments (EDMs) from paramagnetic AMO and neutron EDM experiments. The charm and bottom quark EDMs generate CP-odd photon-gluon operators and light quark EDMs at the c- and b-quark ...
