Supersymmetric gauged matrix models from dimensional reduction on a sphere

Cyril Closset, Dongwook Ghim, Rak-Kyeong Seong

It was recently proposed that N=1 supersymmetric gauged matrix models have a duality of order four - that is, a quadrality - reminiscent of infrared dualities of SQCD theories in h…

How to prove that the LHC did not discover dark matter

Doojin Kim, Konstantin T. Matchev

If the LHC is able to produce dark matter particles, they would appear at the end of cascade decay chains, manifesting themselves as missing transverse energy. However, such "dark…

NNLO QCD corrections to the transverse momentum distribution of weak gauge bosons

A. Gehrmann-De Ridder, T. Gehrmann, E. W. N. Glover +2

The transverse momentum spectra of weak gauge bosons and their ratios probe the underlying dynamics and are crucial in testing our understanding of the Standard Model. They are an…

Combining initial-state resummation with fixed-order calculations of electroweak corrections

Christian W. Bauer, Nicolas Ferland, Bryan R. Webber

We present a resummation of those double-logarithmically enhanced electroweak correction that arise in pp colliders because protons are not SU(2) singlets, by solving DGLAP equatio…
