A bstract Searches for dark photons provide serendipitous discovery potential for other types
of vector particles. We develop a framework for recasting dark photon searches to obtain …

Searches are performed for both promptlike and long-lived dark photons, A′, produced in
proton-proton collisions at a center-of-mass energy of 13 TeV, using A′→ μ+ μ-decays and …

We search for single-photon events in 53 fb-1 of e+ e-collision data collected with the
BABAR detector at the PEP-II B-Factory. We look for events with a single high-energy photon …

Searches are performed for both promptlike and long-lived dark photons, A′, produced in
proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for …

Electron-positron angular correlations were measured for the isovector magnetic dipole 17.6
MeV (J π= 1+, T= 1) state→ ground state (J π= 0+, T= 0) and the isoscalar magnetic dipole …

Dark sectors charged under a new Abelian interaction have recently received much
attention in the context of dark matter models. These models introduce a light new mediator …

A bstract High-energy colliders offer a unique sensitivity to dark photons, the mediators of a
broken dark U (1) gauge theory that kinetically mixes with the Standard Model (SM) …

Abstract A sample of 1.69× 10 7 fully reconstructed π 0→ γ e+ e− decay candidates
collected by the NA48/2 experiment at CERN in 2003–2004 is analyzed to search for the …

We perform an extensive survey of nonstandard Higgs decays that are consistent with the
125 GeV Higgs-like resonance. Our aim is to motivate a large set of new experimental …

Recently a 6.8 σ anomaly has been reported in the opening angle and invariant mass
distributions of e+ e-pairs produced in Be 8 nuclear transitions. The data are explained by a …
