Abstract

The precision measurements of the properties of the recently discovered Higgs-like boson will be central to the future LHC physics program. In parallel the search for New Physics beyond the SM will continue. Higher luminosity will extend the mass reach and allow sensitive searches for possible subtle signatures for new physics. In this paper we review the potential sensitivity of CMS to a selection of relevant future physics scenarios accessible with the LHC upgrades and a correspondingly upgraded CMS detector.

Highlights

  • With the first 10 fb-1 of data at 7 and 8 TeV ATLAS and CMS have dramatically changed the picture of the search for a standard model (SM) Higgs boson, excluding all masses below 600 GeV except for a narrow mass interval around 125 GeV

  • Following the discovery of a Higgs-like boson, the precision measurements of the properties of this new particle will be central to the LHC physics program

  • This benchmark uses the explicit assumption that no new physics is present and there are no additional loops in the production or decay of the Higgs boson

Summary

Introduction

With the first 10 fb-1 of data at 7 and 8 TeV ATLAS and CMS have dramatically changed the picture of the search for a standard model (SM) Higgs boson, excluding all masses below 600 GeV except for a narrow mass interval around 125 GeV. Both ATLAS and CMS observe a new boson with a significance of about five sigma [1,2]. Gluinos and squarks with masses below 1 TeV are excluded in simple Supersymmetry models while scenarios with 3rd generation squarks below 1 TeV are still compatible with the data. A more complete account of the CMS expected performance can be found in [4]
