LPC Fellows



Nikos Varelas

What I will be working on:

During my fellowship at LPC, I will be working on the search for a low-mass Standard Model Higgs boson produced in association with an electroweak vector boson (W,Z), with the Higgs decaying to b-bbar. Together with my group at UIC, and in collaboration with other groups at LPC and around the world, I plan to investigate the production of highly boosted Higgs boson where the b-bbar system is reconstructed as one “fat” jet, utilizing jet substructure techniques to reconstruct the final state. Moreover, I plan to continue working on quark compositeness searches using the dijet system.

My role in CMS past and present:

I joined CMS in 2005 and, together with my group at UIC, have contributed to several activities related to the High Level Trigger–from its building and commissioning phase to trigger menu development and performance studies, and to jet reconstruction and performance studies. In addition, I have contributed to, and published results on, QCD jet measurements and searches for quark compositeness with the 2010 and 2011 data, setting the most comprehensive set of limits on the contact interaction scale to date. I have served as co-convener of the Jets and Missing ET Physics Object Group (2007), co-convener of the QCD Physics Analysis Group (2008-2009), and member of the Publications Committee (2010-2011).
