Secret interactions of neutrinos with light gauge boson at the DUNE near detector [PDF]

Physical Review D, 2018
Secret interactions of neutrinos with light new gauge bosons, $Z^\prime$, can lead to a rich phenomenology in supernova explosion as well as in the early universe. This interaction can also lead to new decay modes for charged mesons, $\pi^+ (K^+) \to e^+

The dark side of the proton

Journal of High Energy Physics, 2022
We study the sensitivity of the High-Luminosity LHC to a light baryonic dark photon B, primarily coupled to quarks, as a constituent of the proton. This is achieved by allowing for a dark photon parton distribution function (PDF) in the PDF evolution ...

Trinification from E 6 symmetry breaking

Journal of High Energy Physics, 2023
In the context of E6 Grand Unified Theories (GUTs), an intriguing possibility for symmetry breaking to the Standard Model (SM) group involves an intermediate stage characterized by either SU(3) × SU(3) × SU(3) (trinification) or SU(6) × SU(2).

Cavity QED with quantum gases: new paradigms in many-body physics [PDF]

Advances in Physics, 2021
We review the recent developments and the current status in the field of quantum-gas cavity QED. Since the first experimental demonstration of atomic self-ordering in a system composed of a Bose–Einstein condensate coupled to a quantized electromagnetic ...

Weyl’s gauge argument [PDF]

, 2013
The standard U(1) “gauge principle” or “gauge argument” produces an exact potential A=dλ and a vanishing field F=ddλ=0. Weyl has his own gauge argument, which is sketchy, archaic and hard to follow; but at least it produces an inexact potential A and a ...

Measuring properties of a dark photon from semi-invisible decay of the Higgs boson

Journal of High Energy Physics, 2022
Considerable efforts have been dedicated to discovering a dark photon via the decay of the Higgs boson to a photon and an invisible particle. A subject that is still mostly unexplored is which properties of the dark photon could be measured at the LHC if

Anomalous neutral gauge boson interactions and simplified models [PDF]

Physical Review D, 2017
Trilinear Z boson interactions are sensitive probes both of new sources of C P violation in physics beyond the standard model and of new particle thresholds.

Dark radiation constraints on portal interactions with hidden sectors [PDF]

Journal of Cosmology and Astroparticle Physics, 2022
We update dark radiation constraints on millicharged particle (MCP) and gauged baryon-number-minus-lepton-number (B-L) extensions of the Standard Model (SM).

Gauge Symmetry Breaking in Gauge Theories---In Search of Clarification [PDF]

, 2011
The paper investigates the spontaneous breaking of gauge symmetries in gauge theories from a philosophical angle. Local gauge symmetry itself cannot break spontaneously in quantized gauge theories according to Elitzur's theorem---even though the notion ...

Anomalous dimension of a general effective gauge theory. Part I. Bosonic sector [PDF]

Journal of High Energy Physics
We classify the physical operators of the most general bosonic effective gauge theory up to dimension six using on-shell methods. Based on this classification, we compute the complete one-loop anomalous dimension employing both on-shell unitarity-based ...
