In 1938, Stueckelberg introduced a scalar field which makes an Abelian gauge theory
massive but preserves gauge invariance. The Stueckelberg mechanism is the introduction of …

SOFTSUSY is a program which accurately calculates the spectrum of superparticles in the
Minimal Supersymmetric Standard Model (MSSM). The program solves the renormalisation …

We present the next-to-next-to-leading order (NNLO) corrections to the total cross section for
(pseudo-) scalar Higgs boson production using an alternative method than those used in …

The four LEP Collaborations, ALEPH, DELPHI, L3 and OPAL, have collected a total of 2461
pb− 1 of e+ e− collision data at centre-of-mass energies between 189 and 209 GeV. The …

If the Higgs mass mH is as low as suggested by present experimental information, the
Standard Model ground state might not be absolutely stable. We present a detailed analysis …

We study the muon anomalous magnetic dipole moment in supersymmetric theories. The
impact of the recent Brookhaven E821 experimental measurement on both model …

The quest for the Higgs boson of the Standard Model, which was a cornerstone in the
physics programme at particle colliders operating at the energy frontier for several decades …

We consider the transverse-momentum (qT) distribution of Higgs bosons produced at
hadron colliders. We use a formalism that uniformly treats both the small-qT and large-qT …

We compute the O (α tα s) two-loop corrections to the neutral Higgs boson masses in the
Minimal Supersymmetric extension of the Standard Model. An appropriate use of the …

The contributions of virtual corrections and soft gluon emission to the inclusive Higgs
production cross section pp-> H+ X are computed at next-to-next-to-leading order in the …
