Probing Standard Model and Beyond with Reactor CE$\nu$NS Data of CONUS+ experiment

Abstract

We explore the potential of reactor antineutrino-induced Coherent Elastic Neutrino-Nucleus Scattering (CE$\nu$NS) data from the CONUS+ experiment to investigate both the Standard Model (SM) and Beyond Standard Model (BSM) scenarios. Alongside CE$\nu$NS, Elastic Neutrino-Electron Scattering (E$\nu$ES) events are also included in our analysis, enabling more stringent constraints on new physics. Within the SM, we examine the weak mixing angle as a precision test of the electroweak sector. For BSM scenarios, we constrain the parameter space of light mediators arising from neutrino generalized interactions (NGI), while also setting limits on the electromagnetic properties of neutrinos, including their charge radius, millicharge, and magnetic moment.

18 pages, 7 figures, 3 tables, V3: analysis updated based on the latest data release from the CONUS+ Collaboration, main conclusions remain unchanged, matches published version in PLB
