Research Interests

My main interests are concerned with work related to the CMS experiement at the Large Hardon Collider (LHC) at CERN. One of the main purposes of CMS detector is to look for new physics beyond the Standard Model (BSM) of particle physics. The Standard Model has allowed physicists to understand the fundamental laws of particle physics; however it does not satisfactorily answer to many questions (like matter anti-matter asymmetry, dark matter and extra-dimensions). Only experimental data collected by the detectors such as the CMS at the LHC, can allow us to search for evidence from BSM.

In this context, I am involved in analyzing data collected by CMS experiment since 2009. My principal interests are divided into two parts; the first part is dedicated to the physics analysis, the second part is the technical analysis.
