DESCRIPTION:Prof. Lesya Shchutska IPHYS LPHE-LS \nTHE LECTURE IS POSTPONED
  TO A LATER DATE TO BE CONFIRMED\nScientific path in particle physics star
 ted for Lesya Shchutska during a bachelor and a master within the LHCb exp
 eriment group led by Prof. Andrey Golutvin at Moscow’s Institute for The
 oretical and Experimental Physics (ITEP). During her PhD\, she worked on d
 eveloping 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 comi
 ng to the University of Florida group\, and later to the ETH Zürich\, and
  concentrated her research on looking for Supersymmetric particles decayin
 g to leptons. In addition\, she worked on the R&D for the future fixed tar
 get facility at CERN – SHiP (Search for Hidden Particles).\nLesya Shchut
 ska Bio:\nLesya Shchutska’s main research interest lies in a future disc
 overy of new particles\, as e.g. dark matter nature\, the sizeable matter-
 antimatter asymmetry and the neutrino masses are not predicted by the stan
 dard model of particle physics. One of the most elegant and compelling ext
 ensions of the standard model was proposed by Prof. Mikhail Shaposhnikov a
 t EPFL. This theory already inspired the design of a new facility at CERN 
 (SHiP)\, and led many experimentalists to hunt for heavy neutrinos – inv
 isible and noninteracting siblings of very light standard model neutrinos.
  With a recently awarded ERC Starting Grant\, Lesya Shchutska is now looki
 ng for the signs of these particles in the huge dataset delivered by the L
 HC.\nJoining EPFL\, Lesya came back to the LHCb Collaboration at CERN at t
 he most exciting times. Currently\, LHCb might be seeing a difference in i
 nteractions of three families of charged leptons. If confirmed\, this will
  be the first sign of physics beyond the standard model at the LHC. The LH
 Cb detector also provides means to look for long-lived heavy neutrinos pro
 duced in the decays of B mesons\, a task almost impossible in the other ex
 periments\, and which is especially exciting as it unveils a favorable reg
 ion 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 p
 articles 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.\n
