Description
The coherent elastic neutrino-nucleus scattering process (CE$\nu$NS) is a powerful probe of the possible new neutral boson in the theory beyond the standard model, which is a possible explanation of the muon $(g−2)_\mu$ anomaly. CE$\nu$NS was first observed in 2017 at the COHERENT experiment by the cesium-iodide (CsI) detector and later in 2020 at the argon (Ar) detector. Recently, the new result of the CsI detector is also updated in 2021.
In this poster, we present the constraints on the parameters of several light boson mediator models obtained from the combined analysis of the latest data of the COHERENT CE$\nu$NS experiment. We consider a variety of vector boson mediator models and also a model with a new light scalar boson mediator. We compare these constraints with the limits obtained in other experiments, and with the values that can explain the muon $(g−2)_\mu$ anomaly in the models where the muon couples to the new boson mediator.
