SUMMARY:"Probing new force mediators: from atomic physics to LHCb"
DESCRIPTION:Featuring Yotam Soreq\, Massachusetts Institute of Technology\n
	\nPart of the HET Seminar Series.\n\nIn this seminar we explore the potenti
	al of probing new force carriers\, which may be the portal to dark sectors\
	, in the LHCb experiment and by precision isotope shift spectroscopy. We pr
	opose an inclusive search for dark photons  at the LHCb experiment. For Run
	 3 of the LHC\, we estimate that LHCb will have sensitivity to large region
	s of the unexplored dark-photon parameter space\, especially in the 210–5
	20 MeV and 10–40 GeV mass ranges.  \n\nIn addition\, we explore the poten
	tial of probing new light force-carriers\, with spin-independent couplings 
	to the electron and the neutron\, using precision isotope shift spectroscop
	y. We show that the result of these measurement can be interpreted as bound
	s on new physics with minimal theory inputs. We apply the method to existin
	g Ca+ data and project its sensitivity to possibly existing new bosons usin
	g narrow transitions in other atoms and ions. Provided no deviation from th
	e standard model\, future measurements could improve the current Ca+ bound 
	by five orders of magnitude and even reach unprecedented sensitivity for bo
	sons within the 10 keV to 10 MeV mass range. \n\nMoreover\, we derive the b
	ounds on new spin-independent interactions in transition frequencies and th
	eir isotopic shifts of hydrogen\, helium\,  some helium-like ions and posit
	ronium.
