Searching for T' in the Little Higgs Model Using Jet Based Information at CMS

PDF Version Also Available for Download.

Description

Recently, the Little Higgs Model has been introduced to try to solve the hierarchy problem. This note describes a study of the Little Higgs Model using jet and E{sub T} based information with the CMS detector at the LHC. The study used Monte Carlo simulations of the physics and CMS detector to explore the capability of CMS to search for T' {yields} Z + t, and t {yields} W + b, W {yields} two jets with T' masses of 1.0 TeV and 1.75 TeV. These final state jets have large transverse momentum with very small spatial separation. To deal with ... continued below

Description

Recently, the Little Higgs Model has been introduced to try to solve the hierarchy problem. This note describes a study of the Little Higgs Model using jet and E{sub T} based information with the CMS detector at the LHC. The study used Monte Carlo simulations of the physics and CMS detector to explore the capability of CMS to search for T' {yields} Z + t, and t {yields} W + b, W {yields} two jets with T' masses of 1.0 TeV and 1.75 TeV. These final state jets have large transverse momentum with very small spatial separation. To deal with such closely spaced hadronic showers, a special jet algorithm was used that was developed to improve the mass resolution and help reduce the background contamination [1]. The focus of this algorithm was to reconstruct parent particles from two hadronic jets in the final state, so the algorithm was modified to work for three jets. A selection criteria was also developed to reduce Z plus multi-jets background. Using the reconstructed top quark, the transverse mass of the T' was formed for Z neutrinos. The signal significance was calculated for an integrated luminosity of ({approx} 300 fb{sup -1}) and for a T' mass of 1.0 TeV.
