New method to measure Higgs mass at CLIC collider

Abstract

A variety of studies is planned at the future Compact Linear Collider (CLIC) e+e− collider with energy up to 3 TeV. One of the studies is the precision Higgs boson mass measurement planned at the first stage of the CLIC project. The traditional method of recoil mass reconstruction was shown to be ineffective in the CLIC experimental conditions. Instead the new method of the Higgs reconstruction using b-quarks jet directions, originally proposed for the ILC, is expected to be especially effective at CLIC. In this report the Monte-Carlo study of the Higgs mass reconstruction is presented. The goal of the study is to evaluate the expected precision of the Higgs boson mass measurement at the CLIC using the new reconstruction method.
