Measurements of Higgs boson production in the decay channel with a pair of $$\uptau $$ τ leptons in proton–proton collisions at $$\sqrt{s}=13$$ s = 13 TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Measurements of Higgs boson production, where the Higgs boson decays into a pair of $$\uptau $$ τ leptons, are presented, using a sample of proton-proton collisions collected with the CMS experiment at a center-of-mass energy of , corresponding to an ...

Associated Higgs boson production with Z boson in the minimal U(1)X extended Standard Model

open access: yesNuclear Physics B, 2023
The minimal U(1)X extension of the Standard Model (SM) is a simple and well-motivated extension of the SM, which supplements the SM with the seesaw mechanism for naturally generating the light neutrino masses and offers various interesting ...

Searching for a leptophobic B boson through η → π0γγ and ηʹ → π0γγ decays [PDF]

open access: yesEPJ Web of Conferences, 2022
The sensitivity of the decays η → π0γγ and ηʹ → π0γγ to a leptophobic B boson in the sub-GeV mass range is summarised in this work. By adding an explicit B-boson resonance exchange to the dominant Standard Model contribution from vector meson exchanges ...

Quantum transport in d-dimensional lattices

open access: yesNew Journal of Physics, 2016
We show that both fermionic and bosonic uniform d -dimensional lattices can be reduced to a set of independent one-dimensional chains. This reduction leads to the expression for ballistic energy fluxes in uniform fermionic and bosonic lattices.

Structures of the massive vector boson propagators at finite temperature illuminated by the Goldstone equivalence gauge

open access: yesJournal of High Energy Physics, 2020
Inspired by the Goldstone equivalence gauge, we study the thermal corrections to an originally massive vector boson by checking the poles and branch cuts. We find that part of the Goldstone boson is spewed out from the longitudinal polarization, becoming

Non-factorizable virtual corrections to Higgs boson production in weak boson fusion beyond the eikonal approximation

open access: yesJournal of High Energy Physics, 2023
Non-factorizable virtual corrections to Higgs boson production in weak boson fusion at next-to-next-to-leading order in QCD were estimated in the eikonal approximation [1]. This approximation corresponds to the expansion of relevant amplitudes around the

Search for a heavy pseudoscalar Higgs boson decaying into a 125 GeV Higgs boson and a Z boson in final states with two tau and two light leptons at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2020
A search is performed for a pseudoscalar Higgs boson, A, decaying into a 125 GeV Higgs boson h and a Z boson. The h boson is specifically targeted in its decay into a pair of tau leptons, while the Z boson decays into a pair of electrons or muons. A data

Search for a pseudoscalar boson decaying into a Z boson and the 125 GeV Higgs boson in ℓ+ℓ−bb‾ final states

open access: yesPhysics Letters B, 2015
Results are reported on a search for decays of a pseudoscalar A boson into a Z boson and a light scalar h boson, where the Z boson decays into a pair of oppositely-charged electrons or muons, and the h boson decays into bb‾.

Modified models of a free boson string and their solutions

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2019
In this paper we consider the modified models of a free boson string and examine their dynamics. Modified models of the boson string are investigated from the point of view of the second order formalism (the Polyakov action).

Arbitrary synthetic dimensions via multiboson dynamics on a one-dimensional lattice

open access: yesPhysical Review Research, 2021
The synthetic dimension, a research topic of both fundamental significance and practical applications, has been attracting increasing attention in recent years. In this paper, we propose a theoretical framework to construct arbitrary synthetic dimensions,
