Many theories describing physics beyond the Standard Model rely on a large separation of scales. Large scale separation arises in
models with mass-split flavors if the system is conformal in the
ultraviolet but chirally broken in the infrared. Because of the
conformal fixed point, these systems exhibit hyperscaling and a highly
constrained resonance spectrum.
In numerical simulations we...

I will present a computation of the cross section for Higgs production via gluon fusion that is differential in the Higgs momentum and inclusive with respect to associated QCD radiation.
This calculation is carried out through NNLO in perturbative QCD and includes the O(d-4) pieces which are necessary for UV renormalisation and mass factorisation at N3LO.
First, I will discuss the restriction...
We discuss a formalism for the resummation of the Higgs transverse momentum, and more in general of inclusive transverse observables, in direct space up to N3LL accuracy. The talk is based on 1604.02191 and 1705.09127.

"The study of Higgs boson properties form an important part of the LHC program. These studies are not only important for a better understanding of electroweak symmetry breaking mechanism but also for BSM searches. For example, most recently a strategy has been proposed to use LHC measurements of the Higgs transverse momentum distribution to constrain the Yukawa couplings of light-generation...
Studying the pair production of Higgs bosons at the LHC is important as it is sensitive to the Higgs trilinear coupling. It therefore allows for a direct test of the Higgs potential and the mechanism of electroweak symmetry breaking. Since the heavy top limit provides only a poor description of Higgs boson pair production, a precise theoretical description of this process requires the...
The LHC experiments have, so far, measured many of the Higgs couplings and found excellent agreement with the minimally-realized electroweak symmetry breaking (EWSB) mechanism in the Standard Model. Nevertheless, there are important couplings that are currently out of reach which test the nature of EWSB and fermion mass generation. This talk will focus on one such coupling: the hhVV coupling....

The talk will be about the recent calculation of the planar Feynman integrals needed for the two-loop correction to Higgs-plus-jet production (arXiv:1609.06685) with full top-mass dependence, as well as the on-going work on the non-planar parts. I will discuss motivation, integral families, function classes, elliptic integrals, and more.
In this talk we review the current status of QCD corrections for Higgs production and decay at the LHC in the context of BSM physics. These corrections are important for two reasons. First, to appreciate possible deviations in the properties of the observed SM-like states due to the effect colored-BSM particles, such as stops, from virtual corrections. Second, QCD corrections are important for...
After the Higgs boson discovery, LHC can be used as a precision machine to explore its properties. Indeed, in case new resonances will not be found, the only access to New Physics would be via measuring small deviations from the SM predictions. A consistent approach is provided by a bottom-up Effective Field Theory, with dimension six operators built of Standard Model fields (SMEFT). We...

Theoretical uncertainties in the simulation of ttbb production represent one of the main obstacles that still hamper the observation of Higgs-boson production in association with top-quark pairs in the H->b?b. We present a next-to-leading order (NLO) simulation t?tb?b production with massive b-quarks matched to Pythia within the POWHEG method with the hope of reconciling tension between...
