Title: NLO SMEFT in an Event Generator

Abstract: Sherpa is a Monte-Carlo event generator that facilitates experimental comparisons with theoretical predictions.  Hints of New Physics have led us to consider EFTs such as the SMEFT, which is not present within Sherpa. In this work, we have hard-wired NLO SMEFT calculations into Sherpa to allow for future comparisons of experimental data with the SMEFT at dimension 6 and make use of the tools that Sherpa provides to experimentalists. I will describe some notions of dimension 6 SMEFT and give an overview of my work on this project.

TITLE: Bouncing neutrinos in heavy nuclei: exploring the unknown with CE$\nu$NS

ABSTRACT: Since its discovery in 2017, Coherent Elastic neutrino-Nucleus Scattering (CE$\nu$NS) has opened a new window into both nuclear and neutrino physics. With an increasing number of dedicated experiments,
this process provides valuable information not only to confirm Standard Model predictions but also to probe Beyond Standard Model scenarios.

In this talk, we will explore potential signs of new physics within the nuclear aspects of CE$\nu$NS, such as the weak charge and the nuclear form factors, making a fit to the most recent data from the COHERENT collaboration CE$\nu$NS measurements in CsI. Additionally, we will discuss recent indications of CE$\nu$NS detection from ${}^8B$ solar neutrinos in dark matter direct detection experiments like XENONnT and PandaX, focusing on their sensitivity to new scalar and vector mediators. We will also address the sensitivity of other CE$\nu$NS experiments, such as COHERENT, to these BSM scenarios.
