B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays and the extraction of f d /f u at hadron colliders

open access: yesJournal of High Energy Physics
We perform a detailed model-independent phenomenological analysis of B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays. Employing an SU(3) F analysis including symmetry-breaking contributions together with a conservative power counting for various ...

Discovering Higgs bosons of two Higgs Doublet models with Bottom quarks.

open access: yes, 2007
We investigate the prospects of detecting Higgs bosons of two Higgs Doublet models with Bottom quarks at the CERN Large Hadron Collider (LHC)

B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays in QCD factorization

open access: yesJournal of High Energy Physics
Motivated by the first LHCb searches for the rare B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays, we perform a detailed study of these processes within the QCD factorization formalism.

Search for dark matter produced in association with a pair of bottom quarks in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics
A search for dark matter (DM) particles produced in association with bottom quarks is presented. The analysis uses proton-proton collision data at a center-of-mass energy of s $$ \sqrt{s} $$ = 13 TeV, corresponding to an integrated luminosity of 138 fb ...

Heavy quark symmetry behind b → c semileptonic sum rule

open access: yesJournal of High Energy Physics
Lepton flavor universality violations in semileptonic b → c transitions have garnered attention over a decade. For $${R}_{{H}_{c}}={\text{BR}}\left({H}_{b}\to {H}_{c}\tau {\overline{\nu }}_{\tau }\right)/{\text{BR}}\left({H}_{b}\to {H}_{c}{\ell ...

$t\bar{t}b\bar{b}$ hadroproduction with massive bottom quarks with PowHel

open access: yes, 2017
The associated production of top-antitop-bottom-antibottom quarks is a relevant irreducible background for Higgs boson analyses in the top-antitop-Higgs production channel, with Higgs decaying into a bottom-antibottom quark pair.

Higgs boson couplings to top, bottom and charm quarks with the ATLAS detector

open access: yes, 2022
Testing the Yukawa couplings of the Higgs boson to fermions is essential to understand the origin of their masses, and studies are made by exploring the properties of the Higgs boson decays to quark pairs.

Measuring CP violation using quantum state tomography

open access: yesJournal of High Energy Physics
We investigate direct CP violation in neutral meson decays by reconstructing the associated density matrices and measuring their difference using the trace distance.
