- POSTPONED - Particle hunt: looking for the rare and invisible
THE LECTURE IS POSTPONED TO A LATER DATE TO BE CONFIRMED
Scientific path in particle physics started for Lesya Shchutska during a bachelor and a master within the LHCb experiment group led by Prof. Andrey Golutvin at Moscow’s Institute for Theoretical and Experimental Physics (ITEP). During her PhD, she worked on developing a new detector for a balloon-borne experiment, graduating from EPFL in the group of Prof. Tatsuya Nakada in 2012. Exploring new ways for new physics searches, and especially for dark matter particle searches, Lesya joined the CMS experiment at the Large Hadron Collider (LHC) by coming to the University of Florida group, and later to the ETH Zürich, and concentrated her research on looking for Supersymmetric particles decaying to leptons. In addition, she worked on the R&D for the future fixed target facility at CERN – SHiP (Search for Hidden Particles).
Lesya Shchutska Bio:
Lesya Shchutska’s main research interest lies in a future discovery of new particles, as e.g. dark matter nature, the sizeable matter-antimatter asymmetry and the neutrino masses are not predicted by the standard model of particle physics. One of the most elegant and compelling extensions of the standard model was proposed by Prof. Mikhail Shaposhnikov at EPFL. This theory already inspired the design of a new facility at CERN (SHiP), and led many experimentalists to hunt for heavy neutrinos – invisible and noninteracting siblings of very light standard model neutrinos. With a recently awarded ERC Starting Grant, Lesya Shchutska is now looking for the signs of these particles in the huge dataset delivered by the LHC.
Joining EPFL, Lesya came back to the LHCb Collaboration at CERN at the most exciting times. Currently, LHCb might be seeing a difference in interactions of three families of charged leptons. If confirmed, this will be the first sign of physics beyond the standard model at the LHC. The LHCb detector also provides means to look for long-lived heavy neutrinos produced in the decays of B mesons, a task almost impossible in the other experiments, and which is especially exciting as it unveils a favorable region for these new particles masses. Already at EPFL, Lesya is set out to measure the known neutrinos produced in the LHC collisions, by helping to build and operate a new dedicated experiment – SND@LHC. These elusive particles already brought a lot of surprises in the past, while remaining the least studied known elementary particles – this offers a new ground for testing standard model of particle physics beyond what’s achieved up to now.
