Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Mean-field instability of trapped dilute boson-fermion mixtures

open access: yes, 2001
The influence of boson-boson and boson-fermion interactions on the stability of a binary mixture of bosonic and fermionic atoms is investigated. The density profiles of the trapped mixture are obtained from direct numerical solution of a modified Gross ...

Was the Higgs boson discovered? [PDF]

open access: yes, 2015
The standard model has postulated the existence of a scalar boson, named the Higgs boson. This boson plays a central role in a symmetry breaking scheme called the Brout-Englert-Higgs mechanism (or the Brout-Englert-Higgs-Guralnik-Hagen-Kibble mechanism ...

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,

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Associated Higgs plus vector boson test of a fermiophobic Higgs boson

open access: yes, 2012
Production in association with an electroweak vector boson V is a distinctive mode of production for a Higgs boson H without tree-level couplings to fermions, known as a fermiophobic Higgs boson.

Measurements of WH and ZH production in the $$H \rightarrow b\bar{b}$$ H → b b ¯ decay channel in pp collisions at $$13\,\text {Te}\text {V}$$ 13 Te with the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Measurements of the Standard Model Higgs boson decaying into a $$b\bar{b}$$ b b ¯ pair and produced in association with a W or Z boson decaying into leptons, using proton–proton collision data collected between 2015 and 2018 by the ATLAS detector, are ...

On three dimensional bosonization [PDF]

open access: yesPhys.Lett. B409 (1997) 257-264, 1997
We discuss Abelian and non-Abelian three dimensional bosonization within the path-integral framework. We present a systematic approach leading to the construction of the bosonic action which, together with the bosonization recipe for fermion currents, describes the original fermion system in terms of vector bosons.

Diagrammatic Schemes for Nonlinear Optical Interactions

open access: yesJournal of Raman Spectroscopy, EarlyView.
Conventional diagrammatic approaches (blue frames in the figure) to semi‐classical nonlinear optical interactions emphasize either the bra and ket matter states (double‐sided Feynman diagrams and Liouville pathways) or the frequencies of the bra and ket radiative processes between energy levels (Albrecht notation). We propose a field‐type modification (

Limits on Anomalous WWgamma and WWZ Couplings [PDF]

open access: yes, 1998
Limits on the anomalous WWgamma and WWZ couplings are presented from a simultaneous fit to the data samples of three gauge boson pair final states in pbar-p collisions at sqrt(s)=1.8 TeV: Wgamma production with the W boson decaying to enu or munu, W ...
