Research Description

I have been working in the ZEUS collaboration, an experiment using the data from the electron-proton collider HERA located at the DESY laboratory in Germany. There the main emphasis of the study was to investigate the internal structure of protons, which consists of fundamental particles, namely quarks and gluons that bound the quarks together. Also I have studied the interaction between quarks and gluons. On the technical side of the experiment, I have been maintaining the so-called trigger system, which selects relevant events among the collisions and background.

I have just joined this laboratory from April 2007. I would like to utilise my experience for one of the main project in this lab, the ATLAS experiment, on the highest energy proton-proton collider, the LHC at CERN, Geneva. The objective of the collider is to achive the highest energy states, which have never been explored by human being and produce new particles and interaction. It is expected to find new interaction such as the Higgs particle, which explaining the origin of mass. I personally wish to find something totally unexpected from the theoretical point of view, since that's the raison d'être for experimentalists! I will take part in the ATLAS experiment through the commissioning and understanding of the endcap muon trigger system this lab has participated in construction.
