The Low-Scale Approach to Neutrino Masses

TL;DR: A short review of low-scale models of neutrino mass generation can be found in this paper, with view on their phenomenological potential, including signatures associated to direct neutrinos mass messenger production at the LHC, as well as messenger-induced lepton flavor violation processes.

NNLO QCD corrections to Higgs boson production at large transverse momentum

TL;DR: In this article, the second-order QCD corrections to the production of a Higgs boson recoiling against a parton with finite transverse momentum are derived, working in the effective field theory in which the top quark contributions are integrated out.

Closing in on singlet scalar dark matter: LUX, invisible Higgs decays and gamma-ray lines

TL;DR: In this paper, the authors study the implications of the Higgs discovery and of recent results from dark matter searches on real singlet scalar dark matter, and show that direct and indirect searches (especially the search for monochromatic gamma-ray lines) will play a key role in closing the residual parameter space in the near future.

Constraining anomalous Higgs boson couplings to the heavy flavor fermions using matrix element techniques

TL;DR: In this article, the authors investigate anomalous interactions of the Higgs boson with heavy fermions, employing shapes of kinematic distributions and present applications of event generation, reweighting techniques for fast simulation of anomalous couplings, as well as matrix element techniques for optimal sensitivity.

Electroweak and conformal symmetry breaking by a strongly coupled hidden sector

TL;DR: In this paper, a model with a combined breaking of conformal and electroweak symmetry by a strongly coupled hidden sector was proposed, where dark matter candidates were detected in the form of dark pions, whose stability was guaranteed by the flavor symmetry of hidden quark sector.

PYTHIA 6.4 Physics and Manual

TL;DR: The Pythia program as mentioned in this paper can be used to generate high-energy-physics ''events'' (i.e. sets of outgoing particles produced in the interactions between two incoming particles).

The anti-$k_t$ jet clustering algorithm

TL;DR: The anti-k-t algorithm as mentioned in this paper behaves like an idealised cone algorithm, in that jets with only soft fragmentation are conical, active and passive areas are equal, the area anomalous dimensions are zero, the non-global logarithms are those of a rigid boundary and the Milan factor is universal.

A Brief Introduction to PYTHIA 8.1

TL;DR: PYTHIA 8 represents a complete rewrite in C++, and does not yet in every respect replace the old code, but does contain some new physics aspects that should make it an attractive option especially for LHC physics studies.
