Higgs pair production in gluon fusion to higher orders in Higgs Effective Field Theory
Ilaria Brivio, Ramona Gröber, Konstantin Schmid
Higgs pair production offers the opportunity to probe correlations among the couplings of one or two Higgs bosons to fermions and gauge bosons. In this context, it serves as a powe…
Complete two-loop Yukawa-induced running of the Higgs-gluon coupling in SMEFT
Stefano Di Noi, Barbara Anna Erdelyi, Ramona Gröber
We compute the two-loop renormalisation group equation for the effective Higgs to gluon coupling in Standard Model Effective Field Theory. Concretely, we present the contributions…
Multi-Higgs Amplitudes Bootstrapped: Dissecting SMEFT and HEFT
Ramona Gröber, Alejo N. Rossia, Michał Ryczkowski
The precise measurement of the Higgs boson properties requires a robust framework to parametrize possible deviations from Standard Model (SM) predictions in the most model-independ…
Two-loop BSM contributions to Higgs pair production in the aligned THDM
Giuseppe Degrassi, Ramona Gröber, Pietro Slavich
We study the impact of the two-loop corrections controlled by the BSM Higgs couplings on the cross section for the production of a pair of SM-like Higgs bosons via gluon fusion in…
Constraining four-heavy-quark operators with top-quark, Higgs, and electroweak precision data
Stefano Di Noi, Hesham El Faham, Ramona Gröber +2
We establish constraints on the dimension-six four-heavy-quark operators in the Standard Model Effective Field Theory (SMEFT) by synthesising LHC measurements of top-quark and sing…
Mapping between schemes in the Standard Model Effective Field Theory
S. Di Noi, R. Gröber, P. Olgoso
We explore the relation between two distinct prescriptions for in dimensional regularization -- the Breitenlohner Maison t'Hooft Veltman (BMHV) scheme and Naive Dimensional R…
Probing New Physics with the Electron Yukawa coupling
Barbara Anna Erdelyi, Ramona Gröber, Nudzeim Selimovic
A dedicated run of a future electron-positron collider (FCC-ee) at a center-of-mass energy equal to the Higgs boson mass would enable a direct measurement of the electron Yukawa co…
Two-loop running effects in Higgs physics in Standard Model Effective Field Theory
Stefano Di Noi, Ramona Gröber, Manoj K. Mandal
We consider the renormalization group equations within the Standard Model Effective Field Theory and compute two-loop contributions proportional to the top quark Yukawa coupling fo…
Virtual QCD corrections to : top-quark loops from a transverse-momentum expansion
Giuseppe Degrassi, Ramona Gröber, Marco Vitti
We present the virtual corrections due to the top-quark loops for the process at next-to-leading order in QCD. The associated two-loop box diagrams are computed using a…
Hunting for CP-violating axionlike particle interactions
Luca Di Luzio, Ramona Gröber, Paride Paradisi
The impact of axion-like particles (ALPs) on the search of permanent electric dipole moments (EDMs) of molecules, atoms, nuclei and nucleons is systematically investigated. We clas…
Top quark mass effects in at two loops and off-shell Higgs interference
Ramona Gröber, Andreas Maier, Thomas Rauh
We consider top-quark mass effects in the Higgs-interference contribution to -boson pair production in gluon fusion. While this production mechanism is formally of next-to-next-…
