Signals with six bottom quarks for charged and neutral Higgs bosons [PDF]

open access: yesJournal of High Energy Physics, 2020
In extensions of two Higgs doublet models with vectorlike quarks, the decays of vectorlike quarks may easily be dominated by cascade decays through charged or neutral Higgs bosons leading to signatures with 6 top or bottom quarks.

More on heavy tetraquarks in lattice QCD at almost physical pion mass

open access: yesEPJ Web of Conferences, 2018
We report on our progress in studying exotic, heavy tetraquark states, qq′ Q̅Q̅′. Using publicly available dynamical nf = 2 + 1 Wilson-Clover gauge configurations, generated by the PACS-CS collaboration, with pion masses ≃ 164, 299 and 415 MeV, we extend

Search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks using a matrix element method. [PDF]

open access: yesEur Phys J C Part Fields, 2015
A search for a standard model Higgs boson produced in association with a top-quark pair and decaying to bottom quarks is presented. Events with hadronic jets and one or two oppositely charged leptons are selected from a data sample corresponding to an ...

Analytic decay width of the Higgs boson to massive bottom quarks at next-to-next-to-leading order in QCD [PDF]

open access: yesJournal of High Energy Physics, 2023
The Higgs boson decay to a massive bottom quark pair provides the dominant contribution to the Higgs boson width. We present an exact result for such a decay induced by the bottom quark Yukawa coupling with next-to-next-to-leading order (NNLO) QCD ...

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 ...

Associated production of a W boson and massive bottom quarks at next-to-next-to-leading order in QCD [PDF]

open access: yesPhysical Review D, 2022
We present the first calculation for the hadroproduction of a $W$ boson in association with a massive bottom ($b$) quark-antiquark pair at next-to-next-to-leading order (NNLO) in QCD perturbation theory.

Search for nonresonant Higgs boson pair production in final state with two bottom quarks and two tau leptons in proton-proton collisions at $\sqrt{s}$ = 13 TeV [PDF]

open access: yes, 2022
A search for the nonresonant production of Higgs boson pairs (HH) via gluon-gluon and vector boson fusion processes in final states with two bottom quarks and two tau leptons is presented. The search uses data from proton-proton collisions at a center-of-

$B_c^+$ Formation from Random Charm and Anti-bottom Quarks in the Quark-Gluon Plasma [PDF]

open access: yes, 2021
We study the B + c production in Pb-Pb collisions at √ s NN = 5 . 02 TeV. In the quark-gluon plasma (QGP) produced in heavy-ion collisions, heavy quarks make random motions with the energy loss.
