Abstract
New heavy resonances are predicted by many extensions of the standard model of particle physics. Recent results for high mass resonance searches with the Compact Muon Solenoid detector, in the diphoton, dilepton, dijet and ttbar channels, are discussed. Limits for numerous benchmark models are presented.
Highlights
We present recent results for high mass resonance searches with the Compact Muon Solenoid (CMS) detector
The limits on the cross section are translated into lower limits on the model parameters (Fig. 2), where M1 is the mass of the first graviton excitation, and kis a dimensionless parameter which quantifies the strength of the graviton coupling to standard model (SM) fields
We perform a general model independent shape-based search for three types of resonances, the differences arising from final state radiation (FSR)
Summary
We present recent results for high mass resonance searches with the Compact Muon Solenoid (CMS) detector. The searches are conducted in a model independent manner, looking for excesses in the diphoton, dilepton, dijet, and tt invariant mass spectra. As no excesses above standard model (SM) expectations are observed, limits are computed, probing a variety of benchmark models, such as those predicting Randall-Sundrum (RS) gravitons [1], extra heavy gauge bosons (Z , W ) [2], and other exotic phenomena
