SUMMARY:Searching for Hidden Dark Sectors at the LHC
DESCRIPTION:Featuring Mariangela Lisanti\, Princeton\n\nPart of the HET Sem
	inar Series.\n\nThe dark matter may be a remnant of strong dynamics that is
	 accessible via a weakly coupled portal. If the hidden-sector states are pr
	oduced at the LHC\, they would undergo a QCD-like shower yielding a spray o
	f stable invisible dark matter along with unstable states that decay back t
	o the Standard Model. Such "semi-visible" jets arise\, for example\, when t
	heir production and decay are driven by a leptophobic Z' resonance; the res
	ulting signature is characterized by significant missing energy aligned alo
	ng the direction of one of the jets. These events are vetoed by the current
	 suite of searches employed by the LHC\, resulting in low acceptance. We de
	monstrate that the transverse mass—computed using the final-state jets an
	d the missing energy—provides a powerful discriminator between the signal
	 and the QCD background.
