Next-to-leading order corrections for gg → ZH with top quark mass dependence

open access: yesPhysics Letters B, 2022
In this work, we present for the first time a calculation of the complete next-to-leading order corrections to the gg→ZH process. We use the method of small mass expansion to tackle the most challenging two-loop virtual amplitude, in which the top quark ...

Aspects of nonlinear effect on black hole superradiance

open access: yesJournal of High Energy Physics, 2020
Under some conditions, light boson fields grow exponentially around a rotating black hole, called the superradiance instability. We discuss effects of nonlinear interactions of the boson on the instability.

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

The Higgs boson couplings: past, present, and future. The relationships between Higgs boson and other known particles as measured by current and future experiments

open access: yesFrontiers in Physics, 2023
The discovery of the Higgs boson, a fundamental particle of the Standard Model, at the Large Hadron Collider (LHC) in 2012, marked a monumental milestone in the field of particle physics.

The $π$ Berry Phase and Topological Excitation in Interacting Boson-Fermion Mixtures [PDF]

open access: yesPhysical Review A 92, 033625 (2015), 2015
The topological property of boson-fermion mixture in a one-dimensional optical superlattice is studied and the topological insulating phase of interacting boson-fermion mixture characterized by a nontrivial Berry phase is identified. The single-particle and boson-fermion exchanging excitation spectrums are calculated and we identify the boson-fermion ...

Twice-iterated boson-exchange scattering amplitudes [PDF]

open access: yes, 2006
We calculate at two-loop order the complex-valued scattering amplitude related to the twice-iterated scalar-isovector boson-exchange between nucleons. In comparison to the once-iterated boson-exchange amplitude it shows less dependence on the scattering ...

Multidimensional bosonization [PDF]

open access: yesAdvances in Physics, 2000
Bosonization of degenerate fermions yields insight both into Landau Fermi liquids, and into non-Fermi liquids. We begin our review with a pedagogical introduction to bosonization, emphasizing its applicability in spatial dimensions greater than one. After a brief historical overview, we present the essentials of the method. Well known results of Landau

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‾.

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC [PDF]

open access: yes, 2013
Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by

Dynamical Boson Stars [PDF]

open access: yesLiving Reviews in Relativity, 2012
AbstractThe idea of stable, localized bundles of energy has strong appeal as a model for particles. In the 1950s, John Wheeler envisioned such bundles as smooth configurations of electromagnetic energy that he called geons, but none were found. Instead, particle-like solutions were found in the late 1960s with the addition of a scalar field, and these ...
