Abstract content

Coherent Elastic Neutrino-Nucleus Scattering (CENNS) is a Standard Model process that, although predicted for decades, has only been detected recently. Now that CENNS has been discovered, it provides a new probe for physics beyond the Standard Model. We study the potential to probe new physics with CENNS through the use of low temperature bolometers at a reactor source. We consider contributions to CENNS due to a neutrino magnetic moment, Non-Standard Interactions that may or may not change flavor, and simplified models containing a massive scalar or vector mediator. Targets consisting of Ge, Zn, Si, CaWO$_4$, and Al$_2$O$_3$ are examined. We present results demonstrating that proposed experiments using bolometers with a reactor source are well positioned to place leading bounds on NSI, and we show the improved bounds that can be placed with various combinations of target materials.
