Probing the Stau-Neutralino Coannihilation Region at the LHC with a soft tau lepton and an ISR jet

Andrés Flórez, Luis Bravo, Alfredo Gurrola +4

We present a feasibility study, to search for dark matter at the LHC, in events with one soft hadronically decaying tau lepton and missing transverse energy recoiling against a har…
