Energy loss of heavy quarks in the isotropic collisional hot QCD medium

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The collisional energy loss of heavy partons (charm and bottom quarks) has been determined within the framework of semi-classical transport theory implying the Bhatnagar–Gross–Krook (BGK) collisional kernel.

Search for heavy charged Higgs bosons decaying into top and bottom quarks in the ATLAS detector

open access: yes, 2021
In this talk a search for charged Higgs bosons in the context of the two-Higgs-Doublet Model is presented. In proton-proton collisions heavy charged Higgs bosons may be produced in association with top and bottom quarks, and, with sufficient mass, may ...

Searches for direct pair production of supersymmetric top and supersymmetric bottom quarks in pp¯ collisions at s=1.96 TeV [PDF]

open access: yes, 2007
We search for direct pair production of supersymmetric top quarks and supersymmetric bottom quarks in proton-antiproton collisions at √s=1.96  TeV, using 295  pb<sup>-1</sup> of data recorded by the Collider Detector at Fermilab (CDF II ...

The Standard Model prediction for the rare decay B → X s ν ν ¯ $$ B\to {X}_s\nu \overline{\nu} $$

open access: yesJournal of High Energy Physics
We present updated and comprehensive Standard Model predictions for the inclusive rare decay B → X s ν ν ¯ $$ B\to {X}_s\nu \overline{\nu} $$ . Using a state-of-the-art determination of the short-distance coefficient, including NLO QCD and electroweak ...

Searches for resonances in final states with top and bottom quarks and for vector-like quarks

open access: yes, 2015
New physics is often expected to be strongly coupled to the third generation quarks. Production of new bosons (W', Z', ...) or vector-like quarks at LHC would then lead to final states with bottom- and top-quarks, potentially accompanied by boosted W, Z ...

Higgs boson couplings to bottom quarks at the ATLAS experiment

open access: yes, 2020
Testing the couplings of the Higgs boson to quarks is important to understand the origin of quark masses. The coupling of the Higgs boson to the bottom quark can be accessed in Higgs boson decays into a pair of b quarks, H->bb.

Searches for scalar top and scalar bottom quarks at LEP2 [PDF]

open access: yes, 1997
Searches for scalar top and bottom quarks have been performed with data collected by the ALEPH detector at LEP. The data sample consists of 21.7 pb^-1 taken at sqrt{s} = 161, 170, and 172~GeV and 5.7 pb^-1 taken at sqrt{s} = 130 and 136~GeV.

Detection of Higgs bosons decaying to bottom quarks

open access: yes, 1986
Several developments affecting the possibility of Higgs detection are discussed. These include the level of certainty about the t quark mass, Monte Carlo programs to generate both signal and background events, and separation and/or enhancement of heavy ...
