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

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 ...

Hybrid Boson Sampling. [PDF]

open access: yesEntropy (Basel)
We propose boson sampling from a system of coupled photons and Bose–Einstein condensed atoms placed inside a multi-mode cavity as a simulation process testing the quantum advantage of quantum systems over classical computers. Consider a two-level atomic transition far-detuned from photon frequency.

The $\pi$ Berry Phase and Topological Excitation in Interacting Boson-Fermion Mixtures

open access: yes, 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.

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‾.

Search for a Higgs Boson Decaying to Weak Boson Pairs at LEP [PDF]

open access: yes, 2003
A Higgs particle produced in association with a Z boson and decaying into weak boson pairs is searched for in 336.4 1/pb of data collected by the L3 experiment at LEP at centre-of-mass energies from 200 to 209 GeV. Limits on the branching fraction of the

On computational complexity and average-case hardness of shallow-depth boson sampling [PDF]

open access: yesQuantum
Boson Sampling, a computational task believed to be classically hard to simulate, is expected to hold promise for demonstrating quantum computational advantage using near-term quantum devices.
