Searches for Leptoquarks, Extra Dimensions, and Dark Matter

TL;DR

This paper reports on multiple searches for exotic phenomena like leptoquarks, extra dimensions, and dark matter using LHC data, setting new limits due to no observed deviations from the standard model.

Contribution

First comprehensive set of LHC search results for leptoquarks, extra dimensions, and dark matter across various final states with new parameter constraints.

Findings

No evidence of physics beyond the standard model.

New limits set on leptoquark and extra dimension models.

Analysis covers data from 2011 and 2012 with up to 19.7 fb$^{-1}$.

Abstract

We present results from several searches for various exotic physics phenomena like large extra dimensions, leptoquarks, and dark matter, in proton-proton collisions at $\sqrt{s}$ = 7 and 8 TeV delivered by the LHC and collected with the CMS detector. Many different final states are analyzed using data collected in 2011 and 2012 corresponding to an integrated luminosity up to 5.0 fb$^{-1}$ and 19.7 fb$^{-1}$. No sign of physics beyond the standard model has been observed so far and the results are used to set new limits on various new physics model parameters.
