Shining Light On Dark Matter with the CMS Experiment
Zeynep Demiragli (CMS Experiment)
TL;DR
This paper reports a search for dark matter and extra dimensions using photon and missing energy events at the CMS experiment, setting new limits but finding no evidence of new physics.
Contribution
It provides the first search of its kind at 8 TeV with photon plus missing energy signatures, improving existing model constraints.
Findings
No deviations from the Standard Model observed.
Improved limits on models of dark matter and extra dimensions.
Enhanced sensitivity compared to previous searches.
Abstract
We present a search for large extra dimensions and dark matter pair-production using events with a photon and missing transverse energy in pp collisions at TeV. This search is done with the data taken by the CMS experiment at the LHC corresponding to an integrated luminosity of 19.6 fb. We find no deviations with respect to the standard model expectation and improve the current limits on several models.
