Alternative angular variables for suppression of QCD multijet events in new physics searches with missing transverse momentum at the LHC

Tai Sakuma, Henning Flaecher, Dominic Smith

We introduce three alternative angular variables-denoted by ${\tilde{\omega }}_{\text{min}}$, ${\hat{\omega }}_{\text{min}}$, and ${\chi }_{\text{min}}$-for QCD multijet event suppression in supersymmetry searche…
