Exact top Yukawa corrections to Higgs boson decay into bottom quarks [PDF]

Physical Review D, 2018
In this paper we present the results of the exact computation of contributions to the Higgs boson decay into bottom quarks that are proportional to the top Yukawa coupling.

Charm and bottom quark masses: An update [PDF]

Physical Review D, 2009
Using new four-loop results for the heavy quark vacuum polarization and new data for bottom quark production in electron-positron annihilation, an update on the determination of charm- and bottom-quark masses through sum rules has been performed. The previous result for the charm-quark mass, $m_c(3 {\rm GeV})= 0.986(13) {\rm GeV}$, based on the lowest ...

Prospects for B s 0 $$ {B}_{(s)}^0 $$ → π 0 π 0 and B s 0 $$ {B}_{(s)}^0 $$ → ηη modes and corresponding CP asymmetries at Tera-Z

Journal of High Energy Physics, 2022
The physics potential of measuring B s 0 $$ {B}_{(s)}^0 $$ → π 0 π 0 and B s 0 $$ {B}_{(s)}^0 $$ → ηη decays via four-photon final states at Tera-Z phase of CEPC or FCC-ee is investigated in this paper.

Top and Bottom Seesaw from Supersymmetric Strong Dynamics [PDF]

, 2013
We propose a top and bottom seesaw model with partial composite top and bottom quarks. Such composite quarks and topcolor gauge bosons are bound states from supersymmetric strong dynamics by Seiberg duality.

Associated production of a Higgs boson decaying into bottom quarks at the LHC in full NNLO QCD [PDF]

, 2017
We consider the production of a Standard Model Higgs boson decaying to bottom quarks in association with a vector boson W ± / Z in hadron collisions.

Higgs-boson production via bottom-quark fusion [PDF]

Physical Review D, 2003
Higgs bosons with enhanced coupling to bottom quarks are copiously produced at hadron colliders via b\bar{b} -> h, where the initial b quarks reside in the proton sea. We revisit the calculation of the next-to-leading-order cross section for this process and argue that the appropriate factorization scale for the b distribution functions is ...

Improved theory predictions and global analysis of exclusive b → sμ + μ − processes

Journal of High Energy Physics, 2022
We provide improved Standard Model theory predictions for the exclusive rare semimuonic processes B → K (*) μ + μ − and B s → ϕμ + μ − . Our results are based on a novel parametrization of the non-local form factors, which manifestly respects a recently ...

Search for a light pseudoscalar Higgs boson produced in association with bottom quarks in pp collisions at sqrt(s) = 8 TeV [PDF]

, 2017
: A search for a light pseudoscalar Higgs boson (A) produced in association with bottom quarks and decaying into a muon pair is reported. The search uses 19.7 fb (cid:0) 1 of proton-proton collisions at a center-of-mass energy of 8 TeV, collected by the ...

Complete analysis on QED corrections to B q → τ + τ −

Journal of High Energy Physics, 2023
Motivated by a dynamical enhancement of the electromagnetic corrections by a power of ΛQCD/m b in B d,s → μ + μ − at next-to-leading order (NLO), we extend the QED factorization effects on the leptonic B meson decays with light muon leptons to tauonic ...
