In this article, we reevaluate supernovae (SN) constraints on the diffusion time of neutrinos for a family of extensions of the Standard Model that incorporate new light scalar and vector mediators. We compute the neutrino mean free path, taking into account medium effects in the neutrino-nucleon scattering cross-section, and a radial dependence of the density, energy, and temperature inside the proto-neutron star to determine the coupling strengths compatible with SN1987A constraints on the… Expand

Effects of correlations on neutrino opacities in nuclear matter
Including nucleon-nucleon correlations due to both Fermi statistics and nuclear forces, we have developed a general formalism for calculating the neutral-current neutrino-nucleon opacities in nuclearExpand
Stellar cooling bounds on new light particles: plasma mixing effects
A bstractStrong constraints on the coupling of new light particles to the Standard Model (SM) arise from their production in the hot cores of stars, and the effects of this on stellar cooling. ForExpand
Crucial Physical Dependencies of the Core-Collapse Supernova Mechanism
We explore with self-consistent 2D Fornax simulations the dependence of the outcome of collapse on many-body corrections to neutrino-nucleon cross sections, the nucleon-nucleon bremsstrahlung rate,Expand
Neutrino interactions in hot and dense matter
We study the charged and neutral current weak interaction rates relevant for the determination of neutrino opacities in dense matter found in supernovae and neutron stars. We establish an efficientExpand
How high is the neutrino floor?
In this paper, we compute the contribution to the coherent elastic neutrino-nucleus scattering cross section from new physics models in the neutrino sector. We use this information to calculate theExpand
Updated constraints on self-interacting dark matter from Supernova 1987A
We revisit SN1987A constraints on light, hidden sector gauge bosons ("dark photons") that are coupled to the standard model through kinetic mixing with the photon. These constraints are realizedExpand
Nucleon-nucleon bremsstrahlung of dark gauge bosons and revised supernova constraints
We calculate the rate of production of hypothetical light vector bosons (LVBs) from nucleon-nucleon bremsstrahlung reactions in hot and dense matter. We use the soft-radiation approximation andExpand

Medium modification of the charged-current neutrino opacity and its implications
Previous work on neutrino emission from proto-neutron stars which employed full solutions of the Boltzmann equation showed that the average energies of emitted electron neutrinos and antineutrinosExpand
Solar neutrino probes of the muon anomalous magnetic moment in the gauged U(1)Lμ−Lτ
Models of gauged U(1)Lμ−Lτ can provide a solution to the long-standing discrepancy between the theoretical prediction for the muon anomalous magnetic moment and its measured value. The extraExpand
