Dr. Liron Barak works on discovering new physics, that will manifest itself either as a new resonance particle (lighter or heavier than the newly discovered Higgs Boson) at the Large Hadron Coliider at CERN or as low mass dark matter at the SENSEI (Sub Electron Noise Skipper-CCD Experimental Instrument) experiment at Fermilab (USA).


Research achievements include: usage of the data that was collected by the ATLAS detector during 2015-2016 in order to search for beyond the standard model Higgs particles either decaying to known particles (as tautau, VV, hh etc) or produced from known particles (as h, Z etc) in various mass ranges.


Future directions include: using LHC data collected in 2015-2018 to search for a new low mass particle using novel techniques such as machine learning to identify the boosted regime. In parallel to analysis of the data collected by the prototype of the SENSEI experiment at Fermilab, working on the construction of a larger scale detector which will take data in an underground mine at Canada (Snolab) reaching an unprecedented sensitivity to low-mass dark matter. She will also participate in the design and construction of MATHUSLA, a very large scale experiment above the LHC ring, looking for long-lived-particles escaping detection of the main detectors.
