Search for Non-resonant excesses from Contact Interactions and Large Extra Dimensions in $\mu^+ \mu^-$ and $e^+ e^-$ Final States in 13 TeV p-p Collisions at CMS

We report results on the search for contact interactions (CI) and large extra dimensions (LED) using data collected during the 2016 run, in proton-proton collisions at the sqrt(s) = 13 TeV by the Compact Muon Solenoid experiment at the Large Hadron Collider at CERN. The analyzed data correspond to luminosities of about 36 $fb^{−1}$. The results, for CI, are interpreted in the context of left-left, left-right, and right-right helicity quark and lepton compositeness models with an energy scale parameter $\Lambda$. The LED model, with exchange of gravitons, is characterized by energy scale parameter $\Lambda_T$. Using information from the invariant mass distribution we set 95{\%} confidence level lower limits on $\Lambda$, for both destructive and constructive interference models, and on $\Lambda_T$.
