Precise predictions for Dirac neutrino mixing
Gauhar Abbas, Mehran Zahiri Abyaneh, Rahul Srivastava
The neutrino mixing parameters are thoroughly studied using renormalization-group evolution of Dirac neutrinos with recently proposed parametrization of the neutrino mixing angles…
Constraining wrong-sign couplings with
Tanmoy Modak, Jorge C. Romão, Soumya Sadhukhan +2
The rare decay has a very small rate in the Standard Model, due to a strong cancellation between the direct and indirect diagrams. Models with a changed co…
Dirac Neutrinos and Dark Matter Stability from Lepton Quarticity
Salvador Centelles Chuliá, Ernest Ma, Rahul Srivastava +1
We propose to relate dark matter stability to the possible Dirac nature of neutrinos. The idea is illustrated in a simple scheme where small Dirac neutrino masses arise from a type…
CP Violation from Flavor Symmetry in a Lepton Quarticity Dark Matter Model
Salvador Centelles Chuliá, Rahul Srivastava, José W. F. Valle
We propose a simple model where neutrinos are predicted to be Dirac fermions. The smallness of their masses follows from a type-I seesaw mechanism and the lepto…
A flavour physics scenario for the 750 GeV diphoton anomaly
Cesar Bonilla, Miguel Nebot, Rahul Srivastava +1
A simple variant of a realistic flavour symmetry scheme for fermion masses and mixings provides a possible interpretation of the diphoton anomaly as an electroweak singlet "flavon"…
Solitons in an effective theory of CP violation
N. Chandra, M. B. Paranjape, R. Srivastava
We study an effective field theory describing CP-violation in a scalar meson sector. We write the simplest interaction that we can imagine, $${\cal L}\sim ε_{i_1\cdots i_5}ε^{μ_1\c…
