Phenomenological profile of scotogenic fermionic dark matter
Anirban Karan, Soumya Sadhukhan, José W. F. Valle
We consider the possibility that neutrino masses arise from the exchange of dark matter states. We examine in detail the phenomenology of fermionic dark matter in the singlet-tripl…
Dynamical scoto-seesaw mechanism with gauged
Julio Leite, Soumya Sadhukhan, José W. F. Valle
We propose a dynamical scoto-seesaw mechanism using a gauged symmetry. Dark matter is reconciled with neutrino mass generation, in such a way that the atmospheric scale arise…
Linear seesaw mechanism from dark sector
A. E. Cárcamo Hernández, Vishnudath K. N., José W. F. Valle
We propose a minimal model where a dark sector seeds neutrino mass generation radiatively within the linear seesaw mechanism. Neutrino masses are calculable, since tree-level contr…
Phenomenology of the simplest linear seesaw mechanism
Aditya Batra, Praveen Bharadwaj, Sanjoy Mandal +2
The linear seesaw mechanism provides a simple way to generate neutrino masses. In addition to Standard Model particles, it includes quasi-Dirac leptons as neutrino mass mediators,…
Large lepton number violation at colliders: predictions from the minimal linear seesaw mechanism
Aditya Batra, Praveen Bharadwaj, Sanjoy Mandal +2
Small neutrino masses can be sourced by a tiny vacuum expectation value of a leptophilic Higgs doublet, and mediated by Quasi-Dirac heavy neutrinos. In such simplest linear seesaw…
Dark-sector seeded solution to the strong CP problem
H. B. Câmara, F. R. Joaquim, J. W. F. Valle
We propose a novel realization of the Nelson-Barr mechanism "seeded'' by a dark sector containing scalars and vector-like quarks. Charge-parity (CP) and a symmetry…
Revamping Kaluza-Klein dark matter in an orbifold theory of flavor
Francisco J. de Anda, Omar Medina, José W. F. Valle +1
We suggest a common origin for dark matter, neutrino mass and family symmetry within the orbifold theory proposed in [arXiv:1910.05605v2,arXiv:2004.06735v2]. Flavor physics is desc…
Physics implications of a combined analysis of COHERENT CsI and LAr data
V. De Romeri, O. G. Miranda, D. K. Papoulias +3
The observation of coherent elastic neutrino nucleus scattering has opened the window to many physics opportunities. This process has been measured by the COHERENT Collaboration us…
W-mass Anomaly in the Simplest Linear Seesaw Mechanism
Aditya Batra, Praveen Bharadwaj, Sanjoy Mandal +2
The simplest linear seesaw mechanism can accommodate the new CDF-II mass measurement. In addition to Standard Model particles, the model includes quasi-Dirac leptons, and a sec…
Physics implications of recent Dresden-II reactor data
Anirban Majumdar, Dimitrios K. Papoulias, Rahul Srivastava +1
Prompted by the recent Dresden-II reactor data we examine its implications for the determination of the weak mixing angle, paying attention to the effect of the quenching function.…
Coherent elastic neutrino-nucleus scattering: Terrestrial and astrophysical applications
M. Abdullah, H. Abele, D. Akimov +272
Coherent elastic neutrino-nucleus scattering (CENS) is a process in which neutrinos scatter on a nucleus which acts as a single particle. Though the total cross section is large…
Towards deconstructing the simplest seesaw mechanism
Sanjoy Mandal, O. G. Miranda, G. Sanchez Garcia +2
The triplet or type-II seesaw mechanism is the simplest way to endow neutrinos with mass in the Standard Model (SM). Here we review its associated theory and phenomenology, includi…
Synergy between cosmological and laboratory searches in neutrino physics
Martina Gerbino, Evan Grohs, Massimiliano Lattanzi +21
The intersection of the cosmic and neutrino frontiers is a rich field where much discovery space still remains. Neutrinos play a pivotal role in the hot big bang cosmology, influen…
High-energy colliders as a probe of neutrino properties
Sanjoy Mandal, O. G. Miranda, G. Sanchez Garcia +2
The mediators of neutrino mass generation can provide a probe of neutrino properties at the next round of high-energy hadron (FCC-hh) and lepton colliders (FCC-ee/ILC/CEPC/CLIC). W…
Interpreting B-anomalies within an extended 331 gauge theory
Andrea Addazi, Giulia Ricciardi, Simone Scarlatella +2
In light of the recent data on neutral current flavour anomalies in decays, we re-examine their quantitative interpretation in terms of…
Nonunitarity of the lepton mixing matrix at the European Spallation Source
Sabya Sachi Chatterjee, O. G. Miranda, M. Tórtola +1
If neutrinos get mass through the exchange of lepton mediators, as in seesaw schemes, the neutrino appearance probabilities in oscillation experiments are modified due to effective…
Scotogenic majorana neutrino masses in a predictive orbifold theory of flavour
Francisco J. de Anda, Omar Medina, José W. F. Valle +1
The use of extra space-time dimensions provides a promising approach to the flavour problem. The chosen compactification of a 6-dimensional orbifold implies a remnant family symmet…

A. E. Cárcamo Hernández, Chandan Hati, Sergey Kovalenko +2
Building up on previous work we propose a Dark Matter (DM) model with gauged matter parity and dynamical gauge coupling unification, driven by the same physics responsible for scot…
Low-energy probes of sterile neutrino transition magnetic moments
O. G. Miranda, D. K. Papoulias, O. Sanders +2
Sterile neutrinos with keV-MeV masses and non-zero transition magnetic moments can be probed through low-energy nuclear or electron recoil measurements. Here we determine the sensi…
The simplest scoto-seesaw model: WIMP dark matter phenomenology and Higgs vacuum stability
