Title: Search for New Physics with CMS and Quantum Sensors
Abstract:
I will present two new highly complementary approaches to search for physics beyond the Standard Model. The searches are enabled by a first-of-its kind reconstruction technique to search for long-lived particles (LLPs) using the Compact Muon Solenoid (CMS) and by new advances in quantum sensing technology to search for axions.
I will first discuss a search for physics beyond the Standard Model by searching for LLPs using a novel technique to reconstruct decays of LLPs in the CMS muon detectors. The innovative LLP reconstruction technique has been shown to be sensitive to a broad range of LLP decay modes and to LLP masses below GeV. The search yields competitive sensitivity for proper lifetime from 0.1m to 1000m with the full Run2 dataset recorded at the LHC.
In the second part of the talk, I will discuss searching for axions with a low noise quantum sensor, SNSPDs (superconducting nanowire single photon detectors). The BREAD (Broadband Reflector Experiment for Axion Detection) experiment searches for axions or dark photons using a parabolic mirror to focus axion-converted photons to the SNSPDs. The SNSPDs allow us to be sensitive to 0.04 – 1 eV axions and dark photons, due to their sensitivity to 0.04 – 1 eV photons. In this talk, I will present the progress towards a first stage dark photon pilot experiment with a focus on SNSPD characterization.
