Hadronic production of top-quark pairs in association with a pair of leptons in the POWHEG BOX framework
Margherita Ghezzi, Barbara Jager, Santiago Lopez Portillo Chavez +2
We present an implementation of () hadronic production at next-to-leading order in QCD matched to parton-shower event generators in the POWHEG BOX…
Vector-like quarks decaying into singly and doubly charged bosons at LHC
Gennaro Corcella, Antonio Costantini, Margherita Ghezzi +3
We investigate the production of vector-like quarks with charge at the LHC and their subsequent decays into new singly or doubly charged bosons plus a heavy quark (top or bot…
Theoretical constraints on the Higgs potential of the general model
Antonio Costantini, Margherita Ghezzi, Giovanni Marco Pruna
This article reviews the theoretical constraints on the scalar potential of a general extension of the Standard Model that encompasses a gauge…
The CLIC Potential for New Physics
J. de Blas, R. Franceschini, F. Riva +100
The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines the benefits of the clean environment of colliders with operation…
Low- and high-energy phenomenology of a doubly charged scalar
Andreas Crivellin, Margherita Ghezzi, Luca Panizzi +2
We explore the phenomenology of an -singlet doubly charged scalar at the high and low energy frontier. Such a particle is predicted in different new physics models, like lef…
Refinements of the Bottom and Strange MSSM Higgs Yukawa Couplings at NNLO
Margherita Ghezzi, Seraina Glaus, Dario Müller +2
We extend the already existing two-loop calculation of the effective bottom-Yukawa coupling in the MSSM. In addition to the resummation of the dominant corrections for large values…
Effective Field Theory with Two Higgs Doublets
Andreas Crivellin, Margherita Ghezzi, Massimiliano Procura
In this article we extend the effective field theory framework describing new physics effects to the case where the underlying low-energy theory is a Two-Higgs-Doublet model. We de…
NLO Higgs Effective Field Theory and kappa-framework
Margherita Ghezzi, Raquel Gomez-Ambrosio, Giampiero Passarino +1
A consistent framework for studying Standard Model deviations is developed. It assumes that New Physics becomes relevant at some scale beyond the present experimental reach and use…
Bounding the Higgs Width Using Effective Field Theory
Margherita Ghezzi, Giampiero Passarino, Sandro Uccirati
An interesting question is how present and future experiments will be able to probe the couplings of the Higgs boson and its intrinsic width at a high level of precision. There is…
eHDECAY: an Implementation of the Higgs Effective Lagrangian into HDECAY
Roberto Contino, Margherita Ghezzi, Christophe Grojean +2
We present eHDECAY, a modified version of the program HDECAY which includes the full list of leading bosonic operators of the Higgs effective Lagrangian with a linear or non-linear…
Effective Lagrangian for a light Higgs-like scalar
Roberto Contino, Margherita Ghezzi, Christophe Grojean +2
We reconsider the effective Lagrangian that describes a light Higgs-like boson and better clarify a few issues which were not exhaustively addressed in the previous literature. In…
The scale of soft resummation in SCET vs perturbative QCD
Marco Bonvini, Stefano Forte, Margherita Ghezzi +1
We summarize and extend previous results on the comparison of threshold resummation, performed, using soft-collinear effective theory (SCET), in the Becher-Neubert approach, to the…
Anomalous Couplings in Double Higgs Production
Roberto Contino, Margherita Ghezzi, Mauro Moretti +3
The process of gluon-initiated double Higgs production is sensitive to non-linear interactions of the Higgs boson. In the context of the Standard Model, studies of this process foc…
Threshold resummation in SCET vs. perturbative QCD: an analytic comparison
Marco Bonvini, Stefano Forte, Margherita Ghezzi +1
We compare threshold resummation in QCD, as performed using soft-collinear effective theory (SCET), to the standard perturbative QCD formalism based on factorization and resummatio…
