Grand Unified Theories (GUTs) are one of the most interesting high-energy completions of
the Standard Model, because they provide a rich, powerful and elegant group-theoretical …

The analytic integration and simplification of multi-loop Feynman integrals to special
functions and constants plays an important role to perform higher order perturbative …

A bstract We discuss the lower Higgs boson mass bounds which come from the absolute
stability of the Standard Model (SM) vacuum and from the Higgs inflation, as well as the …

This report summarizes the work of the Energy Frontier Higgs Boson working group of the
2013 Community Summer Study (Snowmass). We identify the key elements of a precision …

A bstract We study the interactions between strongly interacting massive particle dark matter
and the Standard Model via a massive vector boson that is kinetically mixed with the …

A bstract We study the sensitivity to physics beyond the standard model of precise top-quark
pair production measurements at future lepton colliders. A global effective-field-theory …

We investigate methods to explore the CP nature of the tt¯ h coupling at the LHC, focusing
on associated production of the Higgs boson with att¯ pair. We first discuss the constraints …

A bstract We perform global fits to the parameters of the Constrained Minimal Super-
symmetric Standard Model (CMSSM) and to a variant with non-universal Higgs masses …

PHANTOM is a tree level Monte Carlo for six parton final states at proton–proton, proton–
antiproton and electron–positron colliders at O (αEM6) and O (αEM4αS2) including possible …

A bstract We study lepton flavor observables in the Standard Model (SM) extended with all
dimension-6 operators which are invariant under the SM gauge group. We calculate the …
