CP violation angles from H decays at FCC-ee
Sofia Giappichini, Markus Klute, Matteo Presilla
Measuring charge-parity (CP) violation in Higgs-fermion interactions is a key target of future precision Higgs programs. The decay is particularly sensitive to the CP stru…
Projections of H cross-section at FCC-ee
Sofia Giappichini, Markus Klute, Matteo Presilla +2
The Future Circular Collider (FCC) stands at the forefront of the European Strategy for Particle Physics as the future flagship project at CERN. The H decay, featuring a lar…
Searching for type I seesaw mechanism in a two Heavy Neutral Leptons scenario at FCC-ee
Sehar Ajmal, Patrizia Azzi, Sofia Giappichini +4
This paper investigates the search for heavy neutral leptons (HNL) in the type I seesaw mechanism at the Future Circular Collider in its stage (FCC-ee), considering a lumi…
LHC EFT WG Note: SMEFT predictions, event reweighting, and simulation
Alberto Belvedere, Saptaparna Bhattacharya, Giacomo Boldrini +16
This note gives an overview of the tools for predicting expectations in the Standard Model effective field theory (SMEFT) at the tree level and one loop available through event gen…
Searching for exclusive leptoquarks with the Nambu-Jona-Lasinio composite model at the LHC and HL-LHC
Sehar Ajmal, Jethro Gaglione, Alfredo Gurrola +5
We present a detailed study concerning a new physics scenario involving four fermion operators of the Nambu-Jona-Lasinio type characterized by a strong-coupling ultraviolet fixed p…
Constraints on NJL four-fermion effective interactions from neutrinoless double beta decay
Luca Pacioselli, Orlando Panella, Matteo Presilla +1
We study the contribution of a heavy right-handed Majorana neutrino to neutrinoless double beta decay () via four-fermion effective interactions of Nambu-Jona-Lasinio (NJL) t…
Complementarity between neutrinoless double beta decay and collider searches for heavy neutrinos in composite-fermion models
S. Biondini, S. Dell'Oro, R. Leonardi +4
Composite-fermion models predict excited quarks and leptons with mass scales which can potentially be observed at high-energy colliders like the LHC; the most recent exclusion limi…
Perturbative unitarity bounds for effective composite models
S. Biondini, R. Leonardi, O. Panella +1
In this paper we present the partial wave unitarity bound in the parameter space of dimension-5 and dimension-6 effective operators that arise in a compositeness scenario. These ar…
Like-sign dileptons with mirror type composite neutrinos at the HL-LHC
Matteo Presilla, Roberto Leonardi, Orlando Panella
Within a mirror type assignment for the excited composite fermions the neutrino mass term is built up from a Dirac mass, , which gives the mass of charged lepton component of…
