Electroweak corrections to Higgs-strahlung off W/Z bosons at the Tevatron and the LHC with HAWK

A. Denner, S. Dittmaier, S. Kallweit +1

The associate production of Higgs bosons with W or Z bosons, known as Higgs-strahlung, is an important search channel for Higgs bosons at the hadron colliders Tevatron and LHC for…

Signatures of Exotic Hadrons

Francesco Renga

Hadron spectroscopy represented in the past a major tool for understanding the fundamental symmetries of strong forces. More recently, the interest on this topic has been revitaliz…

Higgs production and decay with a fourth Standard-Model-like fermion generation

A. Denner, S. Dittmaier, A. Muck +5

State-of-the-art predictions for the Higgs-boson production cross section via gluon fusion and for all relevant Higgs-boson decay channels are presented in the presence of a fourth…

Matched predictions for Higgs production via heavy-quark loops in the SM and beyond

Johan Alwall, Qiang Li, Fabio Maltoni

The main Higgs production channel at hadron colliders is gluon fusion via heavy-quark loops. We present the results of a fully exclusive simulation of gluon fusion Higgs production…

SUSY QCD corrections to electroweak gauge boson production with an associated jet at the LHC

Ryan Gavin, Maike K. Trenkel

We study the stability of the neutral- and charged-current Drell-Yan process in association with a jet as a standard candle at the LHC under the inclusion of O(alpha_s) supersymmet…

Standard Model Higgs-Boson Branching Ratios with Uncertainties

A. Denner, S. Heinemeyer, I. Puljak +2

We present an update of the branching ratios for Higgs-boson decays in the Standard Model. We list results for all relevant branching ratios together with corresponding uncertainti…

Neutral Higgs Boson Decays to Squark Pairs reanalyzed

E. Accomando, G. Chachamis, F. Fugel +2

We analyze neutral Higgs boson decays into squark pairs in the minimal supersymmetric extension of the Standard Model and improve previous analyses. In particular the treatment of…

Analytical dispersive construction of amplitude: First order in isospin breaking

Karol Kampf, Marc Knecht, Jiří Novotný +1

Because of their small electromagnetic corrections, the isospin-breaking decays seem to be good candidates for extracting isospin-breaking parameters . This ta…

A comparative study of small x Monte Carlos with and without QCD coherence effects

G. Chachamis, M. Deak, A. Sabio Vera +1

We compare two Monte Carlo implementations of resummation schemes for the description of parton evolution at small values of Bjorken x. One of them is based on the Balitsky-Fadin-K…

Simulating graviton production at hadron colliders

Priscila de Aquino, Kaoru Hagiwara, Qiang Li +1

Spin-2 particles and in particular gravitons are predicted in many new physics scenarios at the TeV scale. Depending on the details of models such new states might show up as a con…
