Dark photon distortions of NOA and T2K neutrino oscillations
Gonzalo Alonso-Álvarez, James M. Cline, Benoit Laurent +1
Dark photons coupling to lepton number difference are a highly studied light dark matter candidate, with potential to be discovered through their impact on terrestrial ne…
Self-interacting dark matter solves the final parsec problem of supermassive black hole mergers
Gonzalo Alonso-Álvarez, James M. Cline, Caitlyn Dewar
Evidence for a stochastic gravitational wave (GW) background, plausibly originating from the merger of supermassive black holes (SMBHs), is accumulating with observations from puls…
The first limit on invisible decays of mesons comes from LEP
Gonzalo Alonso-Álvarez, Miguel Escudero
Motivated by the recent evidence for decays at Belle II, we point out that fully invisible and meson decays are strongly constrained by LEP. A reint…
Nonabelian Kinetic Mixing in a Confining Phase
Gonzalo Alonso-Álvarez, Ruike Cao, James M. Cline +2
Dark matter from a hidden sector with SU() gauge symmetry can have a nonabelian kinetic mixing portal with the standard model. The dark photon becomes massive in the confining p…
The Flavor of QCD Axion Dark Matter
Gonzalo Alonso-Álvarez, James M. Cline, Tianzhuo Xiao
We argue that demanding a consistent cosmological history, including the absence of domain walls and strongly interacting relics at the Peccei-Quinn scale, singles out two concrete…
Distortion of neutrino oscillations by dark photon dark matter
Gonzalo Alonso-Álvarez, Katarina Bleau, James M. Cline
A weakly coupled and light dark photon coupling to lepton charges is an intriguing dark matter candidate whose coherent oscillations alter the dispersion relations of lep…
Sterile neutrino production at small mixing in the early universe
Gonzalo Alonso-Álvarez, James M. Cline
Sterile neutrinos can be produced in the early universe via interactions with their active counterparts. For small active-sterile mixing angles, thermal equilibrium with the standa…
New Physics Searches at Kaon and Hyperon Factories
Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
Gauging lepton flavor SU(3) for the muon
Gonzalo Alonso-Álvarez, James M. Cline
Gauging a specific difference of lepton numbers such as is a popular model-building option, which gives rise to economical explanations for the muon anomalous magnetic mo…
The Strange Physics of Dark Baryons
Gonzalo Alonso-Álvarez, Gilly Elor, Miguel Escudero +3
Dark sector particles at the GeV scale carrying baryon number provide an attractive framework for understanding the origin of dark matter and the matter-antimatter asymmetry of the…
Sterile neutrino dark matter catalyzed by a very light dark photon
Gonzalo Alonso-Álvarez, James M. Cline
Sterile neutrinos () that mix with active neutrinos () are interesting dark matter candidates with a rich cosmological and astrophysical phenomenology. In their simplest…
Unleashing the full power of LHCb to probe Stealth New Physics
Martino Borsato, Xabier Cid Vidal, Yuhsin Tsai +38
In this paper, we describe the potential of the LHCb experiment to detect Stealth physics. This refers to dynamics beyond the Standard Model that would elude searches that focus on…
Collider Signals of Baryogenesis and Dark Matter from Mesons: A Roadmap to Discovery
Gonzalo Alonso-Álvarez, Gilly Elor, Miguel Escudero
Low-scale baryogenesis could be discovered at -factories and the LHC. In the -Mesogenesis paradigm [G. Elor, M. Escudero, and A. E. Nelson, PRD 99, 035031 (2019), arXiv:1810.…
A Supersymmetric Theory of Baryogenesis and Sterile Sneutrino Dark Matter from Mesons
Gonzalo Alonso-Álvarez, Gilly Elor, Ann E. Nelson +1
Low-scale baryogenesis and dark matter generation can occur via the production of neutral mesons at MeV temperatures in the early Universe, which undergo CP-violating oscillati…
Axion couplings to electroweak gauge bosons
G. Alonso-Álvarez, M. B. Gavela, P. Quilez
We determine the model-independent component of the couplings of axions to electroweak gauge bosons, induced by the minimal coupling to QCD inherent to solving the strong CP proble…
