Search for Nonresonant Pair Production of Highly Energetic Higgs Bosons Decaying to Bottom Quarks. [PDF]

open access: yesPhysical Review Letters, 2022
A search for nonresonant Higgs boson (H) pair production via gluon and vector boson (V) fusion is performed in the four-bottom-quark final state, using proton-proton collision data at 13 TeV corresponding to 138  fb^{-1} collected by the CMS experiment ...

Effects of isospin violation in the e + e − → B (*) B ¯ $$ \overline{B} $$ (*) cross sections

open access: yesJournal of High Energy Physics, 2022
Model estimates are obtained for the influence of Coulomb effects on the ratio of the cross sections for the production of charged and neutral B B ¯ $$ \overline{B} $$ and B * B ¯ $$ \overline{B} $$ * pairs in e + e − annihilation.

Soft logarithms in processes with heavy quarks

open access: yesJournal of High Energy Physics, 2022
Observables involving heavy quarks can be computed in perturbative QCD in two different approximation schemes: either the quark mass dependence is fully retained, or it is retained only where needed to regulate the collinear singularity.

Insights on the current semi-leptonic B-decay discrepancies — and how B s → μ + μ − γ can help

open access: yesJournal of High Energy Physics, 2023
B s → μ + μ − γ, measured at high q 2 as a partially reconstructed decay, can probe the origin of the existing discrepancies in semi-leptonic b → s and b → c decays. We perform a complete study of this possibility.

Radial profile of bottom quarks in jets in high-energy nuclear collisions * [PDF]

open access: yesChinese Physics C, High Energy Physics & Nuclear Physics, 2020
Angular correlations between a heavy quark (HQ) and its tagged jet are potentially new tools to gain insight into the in-medium partonic interactions in relativistic heavy-ion collisions. In this work, we present the first theoretical study on the radial

Light-cone sum rules for S-wave B → Kπ form factors

open access: yesJournal of High Energy Physics, 2023
We derive a set of light-cone sum rules relating the S-wave B → Kπ hadronic form factors to the B-meson light-cone distribution amplitudes (LCDAs), taking into account the complete set of LCDAs up to and including twist four. These results complement the

Observation of Higgs Boson Decay to Bottom Quarks. [PDF]

open access: yesPhysical Review Letters, 2018
The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson (VH), and are searched for ...

Search for two Higgs bosons in final states containing two photons and two bottom quarks in proton-proton collisions at 8 TeV [PDF]

open access: yes, 2016
: A search is presented for the production of two Higgs bosons in final states containing two photons and two bottom quarks. Both resonant and nonresonant hypotheses are investigated.

Dispersive analysis of Λ b → Λ(1520) local form factors

open access: yesJournal of High Energy Physics, 2023
We perform an analysis of Λ b → Λ(1520) local form factors. We use dispersive techniques to provide a model-independent parametrisation of the form factors that can be used in the whole kinematic region.
