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 ...

Top, Bottom Quarks and Higgs Bosons [PDF]

, 2002
In this talk, I will discuss possible new physics effects that modify the interaction of Higgs boson(s) with top and bottom quarks, and discuss how to detect such effects in current and future high energy colliders.Comment: LaTeX, 16 pages including 5 ...

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 ...

Deciphering Universal Extra Dimension from the top quark signals at the CERN LHC [PDF]

, 2010
Models based on Universal Extra Dimensions predict Kaluza-Klein (KK) excitations of all Standard Model (SM) particles. We examine the pair production of KK excitations of top- and bottom-quarks at the Large Hadron Collider.

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

Journal of High Energy Physics, 2018
A bstractWe 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.

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 ...

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.

The Experiment Road to the Heavier Quarks and Other Heavy Objects [PDF]

, 2000
After a brief history of heavy quarks, I will discuss charm, bottom, and top quarks in turn. For each one, I discuss its first observation, and then what we have learned about production, hadronization, and decays - and what these have taught us about ...

Resolving charged hadrons in QED — gauge invariant interpolating operators

Journal of High Energy Physics, 2022
Standard interpolating operators for charged mesons, e.g. J B = b ¯ $$ \overline{b} $$ iγ 5 u for B − , are not gauge invariant in QED and therefore problematic for perturbative methods.

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

, 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.
