Direct photon production at next-to-next-to-leading order

John M. Campbell, R. Keith Ellis, Ciaran Williams

We present the first calculation of direct photon production at next-to-next-to leading order (NNLO) accuracy in QCD. For this process, although the final state cuts mandate only t…

Unblinding the Dark Matter Blind Spots

Tao Han, Felix Kling, Shufang Su +1

The dark matter (DM) blind spots in the Minimal Supersymmetric Standard Model (MSSM) refer to the parameter regions where the couplings of the DM particles to the -boson or the…

Exotic Signals of Vectorlike Quarks

Bogdan A. Dobrescu, Felix Yu

Vectorlike fermions are an important target for hadron collider searches. We show that the vectorlike quarks may predominantly decay via higher-dimensional operators into a quark p…

boson mediated dark matter beyond the effective theory

John Kearney, Nicholas Orlofsky, Aaron Pierce

Direct detection bounds are beginning to constrain a very simple model of weakly interacting dark matter---a Majorana fermion with a coupling to the boson. In a particularly st…

Enhanced Higgs associated production with a top quark pair in the NMSSM with light singlets

Marcin Badziak, Carlos E. M. Wagner

Precision measurements of the 125 GeV Higgs resonance recently discovered at the LHC have determined that its properties are similar to the ones of the Standard Model (SM) Higgs bo…

The linear-non-linear frontier for the Goldstone Higgs

M. B. Gavela, K. Kanshin, P. A. N. Machado +1

The minimal sigma model is used as a template for the ultraviolet completion of scenarios in which the Higgs particle is a low-energy remnant of some high-energy dyna…
