When is a boson not a boson? [PDF]

open access: possiblePhysics World, 1995
I have read with interest recent articles about quantum gases in Physics World (July pp37–41, August p2l). I would, however, like to issue a word of warning before the Orwellian chant "even number of fermions bosons, odd number of fermions fermion" becomes too ingrained in the physics folklore.

A new light boson

, 1978
It is pointed out that a global U(1) symmetry, that has been introduced in order to preserve the parity and time-reversal invariance of strong interactions despite the effects of instantons, would lead to a neutral pseudoscalar boson, the "axion," with ...

Quasi-bosons approximate bosons

Reports on Mathematical Physics, 1997
Abstract In the papers [2–5], operators on the Fermi-Fock space that represent a Bose algebra are constructed. Since the operators fulfilling the CCR are unbounded, the Fermi-Fock space is infinite dimensional, and thus the Fermi one-particle space is infinite dimensional.

Boson Stars and Boson Shells

Few-Body Systems, 2018
In this work we present a broad formalism for a study of the models of black holes, boson stars, boson shells and wormholes. The studies of boson stars and boson shells in a theory involving Scalar field, U(1) gauge field and a shelf interacting scalar potential coupled to gravity in the presence of a cosmological constant

BOSON MAPPINGS FOR BOSON SYSTEMS

International Journal of Modern Physics E, 1993
Boson mapping techniques are extended to systems of interacting bosons and then used to extract information regarding unphysical states.

EWK Bosons and the Higgs Boson

2016
As discussed, in Chap. 2, the Higgs boson plays an important role in the process of electroweak symmetry breaking. Correspondingly, the couplings of the electroweak boson to the Higgs boson are noticeably different in structure and strength compared to the Yukawa couplings responsible for the fermion masses.
