Baryon-number-violating nucleon decays in SMEFT extended with a light scalar

Xiao-Dong Ma, Michael A. Schmidt, Weihang Zhang

New light particles have received considerable attention in recent years. Baryon-number-violating (BNV) nucleon decays involving such light particles are able to provide stringent…

An EFT approach to baryon number violation: lower limits on the new physics scale and correlations between nucleon decay modes

Arnau Bas i Beneito, John Gargalionis, Juan Herrero-Garcia +2

Baryon number is an accidental symmetry of the Standard Model at the Lagrangian level. Its violation is arguably one of the most compelling phenomena predicted by physics beyond th…

Squeezing Proton Decay and Neutrino Masses: Upper Bounds on Standard Model Extensions

Arnau Bas i Beneito, John Gargalionis, Juan Herrero-Garcia +1

Baryon and lepton number are excellent low-energy symmetries of the Standard Model (SM) that tightly constrain the form of its extensions. In this paper we investigate the possibil…

Reexamining the search for light ALPs at flavor and forward accelerator experiments

Tong Li, Michael A. Schmidt, Man Yuan

The axion-like particle (ALP) is a well-motivated extension of the Standard Model. In this work, we revisit the sensitivity of forward accelerator experiments to light long-lived A…

Baryon-number-violating nucleon decays in sterile neutrino effective field theories

Tong Li, Michael A. Schmidt, Chang-Yuan Yao

The search for baryon-number-violating (BNV) nucleon decay provides an intriguing probe of new physics beyond the Standard Model (SM). Future neutrino experiments will improve the…
