Axionless strong CP problem solution: the spontaneous CP violation case
Rodolfo Ferro-Hernandez, Stefano Morisi, Eduardo Peinado
We propose an alternative to the axion mechanism for addressing the charge parity (CP) problem in quantum chromodynamics (QCD). Our approach involves imposing CP as an inherent sym…
331 Models and Bilepton Searches at LHC
Roberta Calabrese, Alberto Orso Maria Iorio, Stefano Morisi +2
Despite being remarkable predictive, the Standard Model leaves unanswered several important issues, which motivate an ongoing search for its extensions. One fashionable possibility…
Impact of primordial black holes on heavy neutral leptons searches in the framework of resonant leptogenesis
Roberta Calabrese, Marco Chianese, Jacob Gunn +3
We investigate the effects on sub-TeV resonant leptogenesis of Primordial Black Holes with masses from to g. The latter might dominate the energy content of the…
Limits on light primordial black holes from high-scale leptogenesis
Roberta Calabrese, Marco Chianese, Jacob Gunn +3
We investigate the role that the evaporation of light primordial black holes may have played in the production of the baryon asymmetry of the Universe through the high-scale leptog…
Constraining scalar leptoquarks using COHERENT data
Roberta Calabrese, Jacob Gunn, Gennaro Miele +3
Neutrino-nucleus coherent scattering measurements by the COHERENT collaboration provide us with a unique capability to test various beyond the standard model scenarios. In this wor…
The Radiative Flavor Template at the LHC: Lepton non-universality and g-2
Giacomo Cacciapaglia, Antimo Cagnotta, Roberta Calabrese +5
The Standard Model of Particle Physics and its description of Nature have been recently challenged by a series of precision measurements performed via different accelerator machine…
Unified thermal model for photohadronic neutrino production in astrophysical sources
Damiano F. G. Fiorillo
Astrophysical neutrino fluxes are often modeled as power laws of the energy. This is reasonable in the case of hadronic sources, but it does not capture the behavior in photohadron…
Sensitivity of KM3NeT to Violation of Equivalence Principle
Marco Chianese, Damiano F. G. Fiorillo, Gianpiero Mangano +3
The symmetry of the theory of relativity under diffeomorphisms strongly depends on the equivalence principle. Violation of Equivalence Principle (VEP) can be tested by looking for…
Primordial Black Hole Dark Matter evaporating on the Neutrino Floor
Roberta Calabrese, Damiano F. G. Fiorillo, Gennaro Miele +2
Primordial black holes (PBHs) hypothetically generated in the first instants of life of the Universe are potential dark matter (DM) candidates. Focusing on PBHs masses in the range…
Towards baryogenesis via absorption from Primordial Black Holes
Antonio Ambrosone, Roberta Calabrese, Damiano F. G. Fiorillo +2
Recently Dolgov and Pozdnyakov proposed a new baryogenesis mechanism in which baryon asymmetry is produced without violating baryon number at the Lagrangian level. In this scenario…
The TopFlavor scheme in the context of searches at LHC
Roberta Calabrese, Agostino De Iorio, Damiano F. G. Fiorillo +3
Many extensions of the Standard Model predict the existence of new charged or neutral gauge bosons, with a wide variety of phenomenological implications depending on the model adop…
Heavy decaying dark matter at future neutrino radio telescopes
Marco Chianese, Damiano F. G. Fiorillo, Rasmi Hajjar +3
In the next decades, ultra-high-energy neutrinos in the EeV energy range will be potentially detected by next-generation neutrino telescopes. Although their primary goals are to ob…
IceCube constraints on Violation of Equivalence Principle
Damiano F. G. Fiorillo, Gianpiero Mangano, Stefano Morisi +1
Among the information provided by high energy neutrinos, a promising possibility is to analyze the effects of a Violation of Equivalence Principle (VEP) on neutrino oscillations. W…
Observable features in (ultra)high energy neutrinos due to active-sterile secret interactions
Damiano F. G. Fiorillo, Stefano Morisi, Gennaro Miele +1
We consider the effects of active-sterile secret neutrino interactions, mediated by a new pseudoscalar particle, on high- and ultra high-energy neutrino fluxes. In particular, we f…

Damiano F. G. Fiorillo, Gennaro Miele, Stefano Morisi +1
Ultra High Energy cosmogenic neutrinos may represent a unique opportunity to unveil possible new physics interactions once restricted to the neutrino sector only. In the present pa…
Investigating two heavy neutral leptons neutrino seesaw mechanism at SHiP
Marco Chianese, Damiano F. G. Fiorillo, Gennaro Miele +1
One of the main purposes of SHiP experiment is to shed light on neutrino mass generation mechanisms like the so-called seesaw. We consider a minimal type-I seesaw neutrino mass mec…
Neutrinophilic Dark Matter in the epoch of IceCube and Fermi-LAT
Marco Chianese, Gennaro Miele, Stefano Morisi +1
The recent observation of the blazar TXS 0506+056 suggests the presence of a hard power-law component in the extraterrestrial TeV-PeV neutrino flux, in agreement with the IceCube a…
Neutrino phenomenology from leptogenesis
Franco Buccella, Damiano F. G. Fiorillo, Gennaro Miele +3
Assuming a type-I seesaw mechanism for neutrino mass generation and invoking a baryogengesis via leptogenesis scenario, we consider a reasonable hierarchical structure for Dirac ne…
Interpreting IceCube 6-year HESE data as an evidence for hundred TeV decaying Dark Matter
Marco Chianese, Gennaro Miele, Stefano Morisi
The assumption of a single astrophysical power-law flux to explain the IceCube 6-year HESE extraterrestrial events yields a large spectral index that is in tension with gamma-ray o…
