What I will be working on:

My main effort during 2017 will be directed to analyses involving taus in final state, the observation of the SM H->tautau signal at CMS and search for new phenomena using Run 2 data. Tau leptons, the heaviest leptons in the SM, will play an important role in the physics program that I intend to pursue during 2017. Decay to a pair of tau leptons is one of the dominant ones of the SM Higgs boson, and I am working towards observation of this signal using the whole 2016 dataset. A number of extensions of the SM predict processes that yield experimental signatures involving tau leptons. Using run 2 data collected in 2016 and expected during 2017 I plan to probe BSM sector with tau leptons. I also plan to work on the barrel hadron calorimeter Phase I upgrade, which is intended to take place during long shutdown 2. Based on the feedback received after the first HCAL HATS held in 2016, I know that there is big interest towards such events within CMS. Thus, in 2017 I aim to again organize the HCAL HATS at LPC.

My role in CMS past and present:

I am a member of the CMS collaboration since 2006. I have worked on installation and commissioning of the electromagnetic calorimeter during 2007-2008 years and on the upgrade of the HO calorimeter during the first long shutdown in 2013-2014. Currently am working on Phase I upgrade of the HBHE front-end electronics. In particular, I am responsible for the design and pre-production of the HB and HE calibration units. During Run 1 of the LHC, I worked on search for neutral Higgs bosons in events with pair of tau leptons, probing both the SM and MSSM scenarios. Using both Run 1 and Run 2 data, I performed extensive searches for BSM physics in final states involving tau leptons and number of jets. In particular, results from these analyses constrained a pair production of the third-generation leptoquarks, a pair production of the R-parity violating top squarks, and production of right-handed W boson and a heavy neutrino. Currently, I am working towards observation of the Higgs->tautau signal using Run 2016 dataset.
