We review the solutions of O (N) and U (N) quantum field theories in the large N limit and as
1/N expansions, in the case of vector representations. Since invariant composite fields have …

We review the covariant formulation of quantum field theory, and in particular DeWitt's
background field method, Schwinger's proper-time representations and Pauli-Villars …

Gluon fusion is the main production mechanism for Higgs particles at the LHC. We present
the QCD corrections to the fusion cross sections for the Higgs boson in the Standard Model …

This new edition of The Standard Model and Beyond presents an advanced introduction to
the physics and formalism of the standard model and other non-abelian gauge theories. It …

Higgs boson production at the LHC within the Standard Model and its minimal
supersymmetric extension is reviewed. The predictions for decay rates and production cross …

CMS is a general purpose experiment, designed to study the physics of pp collisions at 14
TeV at the Large Hadron Collider (LHC). It currently involves more than 2000 physicists from …

A bstract We study the ultraviolet behaviour of four-dimensional quantum field theories
involving non-abelian gauge fields, fermions and scalars in the Veneziano limit. In a regime …

We examine the contributions of soft gluons to the Higgs production cross section at the LHC
in the Standard Model and its minimal supersymmetric extension. The soft gluon radiation …

Matching conditions relate couplings to particle masses. We discuss the importance of one-
loop matching conditions in the Higgs boson and top quark sector as well as the choice of …

We present low-energy theorems for the calculation of loop amplitudes with external scalar
or pseudoscalar Higgs bosons which are light compared to the loop particles. Starting from …
