“…For example, alterations are expected at high recoil energies of neutrino-induced interactions at direct DM detection searches [39] which on the other hand may be limited by the current uncertainties of the Atmospheric and DSNB neutrinos. Models involving light mediators are well testable at CEνNS searches and may offer a key solution to LMA-Dark [151,159] as well as implications to DM searches [28,133] and to the neutrino floor [40]. In the same spirit, combined analyses of oscillation and CEνNS data [15,18] concluded that the LMA-D solution is excluded at 3.1σ (3.6σ) for NSI with up (down) quarks.…”

We review standard and non-standard neutrino physics probes that are based on nuclear measurements. We pay special attention on the discussion of prospects to extract new physics at prominent rare event measurements looking for neutrino-nucleus scattering, such as the coherent elastic neutrino-nucleus scattering (CEνNS) that may involve lepton flavor violation (LFV) in neutralcurrents (NC). For the latter processes several appreciably sensitive experiments are currently pursued or have been planed to operate in the near future, like the COHERENT, CONUS, CONNIE, MINER, TEXONO, RED100, vGEN, Ricochet, NUCLEUS etc. We provide a thorough discussion on phenomenological and theoretical studies, in particular those referring to the nuclear physics aspects in order to provide accurate predictions for the relevant experiments. Motivated by the recent discovery of CEνNS at the COHERENT experiment and the active experimental efforts for a new measurement at reactor-based experiments, we summarize the current status of the constraints as well as the future sensitivities on nuclear and electroweak physics parameters, non-standard interactions, electromagnetic neutrino properties, sterile neutrinos and simplified scenarios with novel vector Z or scalar φ mediators. Indirect and direct connections of CEνNS with astrophysics, direct Dark Matter detection and charge lepton flavor violating processes are also discussed.

“…Such limits only apply to mediators with masses sufficiently above the momentum transfer scale of the interaction. Some studies have placed bounds on simplified models including a light Z 0 [11,[21][22][23][24], but they all assume a direct coupling to both neutrinos and first-generation quarks rather than indirect couplings induced from mixing.…”

We examine the current constraints and future sensitivity of coherent elastic neutrino-nucleus scattering (CEνNS) experiments to mixing scenarios involving a Z 0 which interacts via portals with the standard model. We contrast the results against those from fixed target, atomic parity violation, and solar neutrino experiments. We demonstrate a significant dependence of the experimental reach on the Z 0 coupling nonuniversality and the complementarity of CEνNS to existing searches.

“…There have been several previous studies of NSI at nuclear reactors [19,[24][25][26][27]. The aforementioned reactor experiments operate at power ranges from ∼MW-GW, and a range of distance from the reactor core from a few meters to a few tens of meters.…”

We study the complementarity between accelerator and reactor coherent elastic neutrino-nucleus elastic scattering (CEνNS) experiments for constraining new physics in the form of nonstandard neutrino interactions (NSI). First, considering just data from the recent observation by the Coherent experiment, we explore interpretive degeneracies that emerge when activating either two or four unknown NSI parameters. Next, we demonstrate that simultaneous treatment of reactor and accelerator experiments, each employing at least two distinct target materials, can break a degeneracy between up and down flavor-diagonal NSI terms that survives analysis of neutrino oscillation experiments. Considering four flavor-diagonal (ee=μμ) up-and down-type NSI parameters, we find that all terms can be measured with high local precision (to a width as small as ∼5% in Fermi units) by next-generation experiments, although discrete reflection ambiguities persist.
