Large Neutrino-Dark Matter Interactions: From Effective Field Theory to Ultraviolet Completions
K. S. Babu, P. S. Bhupal Dev, Anil Thapa
We develop a general effective field theory (EFT) framework for neutrino-dark matter (DM) interactions, and apply it to systematically find all possible gauge-invariant ultraviolet…
Double Bangs at IceCube as a Window to the Neutrino Mass Origin
Samiur R. Mir, Carlos A. Argüelles, K. S. Babu +1
Neutrino oscillation parameters are subject to renormalization group (RG) evolution, just like all couplings and masses of Standard Model (SM) particles. Within the SM extended wit…
Chiral dark matter and radiative neutrino masses from gauged U(1) symmetry
K. S. Babu, Shreyashi Chakdar, Vishnu P. K
We propose a class of dark matter models based on a chiral gauge symmetry acting on a dark sector. The chiral protects the masses of the dark sector fermions, and als…
A realistic theory of unification through novel intermediate symmetries
K. S. Babu, Borut Bajc, Vasja Susič
We propose a non-supersymmetric GUT with the scalar sector consisting of . Making use of the first representat…
Fermion Masses, Neutrino Mixing and Higgs-Mediated Flavor Violation in 3HDM with Permutation Symmetry
K. S. Babu, Yongcheng Wu, Shiyuan Xu
The Yukawa and scalar sectors of a general -symmetric three-Higgs doublet model (3HDM) are investigated. The Yukawa interactions are constructed in an -invariant way, whi…
Gravitational Wave Signatures of a Chiral Fermion Dark Matter Model
Tomohiro Abe, K. S. Babu, Ajay Kaladharan
Theories in which the dark matter (DM) candidate is a fermion transforming chirally under a gauge symmetry are attractive, as the gauge symmetry would protect the DM mass. In such…
Predictive Dirac Neutrino Spectrum with Strong CP Solution in Unification
K. S. Babu, Rabindra N. Mohapatra, Anil Thapa
We develop a grand unified theory of matter and forces based on the gauge symmetry with parity interchanging the two factor groups. Our main motivation for…
Addressing the Short-Baseline Neutrino Anomalies with Energy-Dependent Mixing Parameters
K. S. Babu, Vedran Brdar, André de Gouvêa +1
Several neutrino experiments have reported results that are potentially inconsistent with our current understanding of the lepton sector. A candidate solution to these so-called sh…
Energy-Dependent Neutrino Mixing Parameters at Oscillation Experiments
K. S. Babu, Vedran Brdar, André de Gouvêa +1
Neutrino mixing parameters are subject to quantum corrections and hence are scale dependent. This means that the mixing parameters associated to the production and detection of neu…
Neutrino Non-Standard Interactions: A Status Report
P. S. Bhupal Dev, K. S. Babu, Peter B. Denton +23
This report summarizes the present status of neutrino non-standard interactions (NSI). After a brief overview, several aspects of NSIs are discussed, including connection to neutri…
