Heavy dark matter in rapidly evolving massive stars

Sandra Robles, Walter Tangarife, Giorgio Busoni

We study the impact of heavy dark matter (DM) captured in massive stars via scattering(s) with the star constituents. We focus on the first stars and use stellar evolution simulati…

Enhancing the Sensitivity to Seesaw Predictions in Gauged Scenarios

Francesco Capozzi, Bhaskar Dutta, Gajendra Gurung +4

New gauge bosons coupled to heavy neutral leptons (HNLs) are simple and well-motivated extensions of the Standard Model. In searches for HNLs in proton fixed-target experiments, we…

Radiative corrections relating leptoquark-fermion couplings probed at low and high energy

Innes Bigaran, Rodolfo Capdevilla, Ulrich Nierste

Scalar leptoquarks (LQ) with masses between 2 TeV and 50 TeV are prime candidates to explain deviations between measurements and Standard-Model predictions in decay observables of…

Tau Tridents at Accelerator Neutrino Facilities

Innes Bigaran, P. S. Bhupal Dev, Diego Lopez Gutierrez +1

We present the first detailed study of Standard Model neutrino tridents involving tau leptons at the near detectors of accelerator neutrino facilities. The rates of these processes…

Mutually elusive: vectorlike antileptons and leptoquarks

Innes Bigaran, Bogdan A. Dobrescu, Alessandro Russo

We study the properties of vectorlike fermions that have the same gauge charges as the Standard Model lepton doublets, but opposite lepton number. These antileptons undergo decays…

Electroweak Scattering at the Muon Shot

Tao Han, Da Liu, Ian Low +1

It has long been recognized that the scattering of electroweak particles at very high energies is dominated by vector boson fusion, which probes the origin of electroweak symmetry…

Hints of Entanglement Suppression in Hyperon-Nucleon Scattering

Qiaofeng Liu, Ian Low

Hyperon ()-nucleon () interactions are crucial for understanding the existence of neutron stars heavier than two solar masses. Amid renewed experimental efforts, we s…

Heavy Neutral Leptons via Axion-Like Particles at Neutrino Facilities

Asli M Abdullahi, André de Gouvêa, Bhaskar Dutta +2

Heavy neutral leptons (HNLs) are often among the hypothetical ingredients behind nonzero neutrino masses. If sufficiently light, they can be produced and detected in fixed-target-l…

The statistics and sensitivity of axion wind detection with the homogeneous precession domain of superfluid helium-3

Joshua W. Foster, Christina Gao, William Halperin +5

The homogeneous precession domain (HPD) of superfluid He has recently been identified as a detection medium which might provide sensitivity to the axion-nucleon coupling $g_{…
