Dear All members,
We are pleased to announce a Journal club by Béranger Dumont.
* Title: "Semi-visible Jets: Dark Matter Undercover at the LHC"
* Speaker: Béranger Dumont (IBS-CTPU)
* Date: 12:00-1:00 PM, 15 May 2015
*Abstract: The dark matter may be a remnant of strong dynamics that is accessible via a weakly coupled portal. If the hidden-sector states are produced at the Large Hadron Collider (LHC), they would undergo a QCD-like shower yielding a spray of stable invisible dark matter along with unstable states that decay back to the Standard Model. Such "semi-visible" jets arise, for example, when their production and decay are driven by a leptophobic Z' resonance; the resulting signature is characterized by significant missing energy aligned along the direction of one of the jets. This paper suggests the transverse mass as a discriminator between the signal and the QCD background.
