Canonical Constraints on Leptonic Cp Violation using UHCR neutrino fluxes
K. R. S. Balaji, G. Couture, C. Hamzaoui
It is shown that one can in principle constrain the CP-violating parameter delta from measurements of four independant |V_{ij}|^2, or three of them and a ratio, in the leptonic sec…
Dynamical CP Violation in the Early Universe and Leptogenesis
K. R. S. Balaji, Tirthabir Biswas, Robert H. Brandenberger +1
In a recent publication, we suggested a mechanism for obtaining dynamical CP violation in the early Universe based on the out-of-equilibrium evolution of complex scalar fields. In…
Scale dependence of the UHECR neutrino flux in extra-dimension models
K. R. S. Balaji, Jukka Maalampi
Ultra high energy cosmic ray (UHECR) neutrino fluxes measured in a fixed target detector can have a scale dependence. In the usual standard model or any extensions of this model (w…
Single Field Baryogenesis and the Scale of Inflation
K. R. S. Balaji, R. H. Brandenberger, Alessio Notari
In the context of inflationary cosmology, we discuss a minimal baryogenesis scenario in which the resulting baryon to entropy ratio is determined by the amplitude of the anisotropi…
Dynamical CP Violation in the Early Universe
K. R. S. Balaji, Tirthabir Biswas, Robert H. Brandenberger +1
Following earlier ideas of Dolgov, we show that the asymmetrical dynamical evolution of fields in the early Universe provides a new source for CP violation. This can lead to baryog…
Dimensional Deconstruction and Neutrino Physics
K. R. S. Balaji
We present a simple observation for neutrino mixings and masses which arises naturally in dimensional deconstruction models. There are two essential ingredients of such models: (i)…
Spectral Dependence of CMB Polarization and Parity
K. R. S. Balaji, Robert H. Brandenberger, Damien A. Easson
The polarization of the cosmic microwave background radiation (CMBR) can serve as a probe for nonstandard parity violating interactions. Many such interactions are predicted in par…
Standard Model CP violation in Polarised b->d l^+ l^-
K. S. Babu, K. R. S. Balaji, I. Schienbein
In the standard model, we study CP violating rate asymmetries in the decay b->d l^+ l^- when one of the leptons is polarised. We find an asymmetry of (5 -- 15)% in the polarised de…
Possible test for CPT invariance with correlated neutral B decays
K. R. S. Balaji, Wilfried Horn, E. A. Paschos
We study breakdown of symmetry which can occur in the decay process with being a CP eigenstate. In this process, the standard model expectati…
Seesaw Neutrino Masses with Large Mixings from Dimensional Deconstruction
K. R. S. Balaji, Manfred Lindner, Gerhart Seidl
We demonstrate a dynamical origin for the dimension-five seesaw operator in dimensional deconstruction models. Light neutrino masses arise from the seesaw scale which corresponds t…
Polarized J/psi production from B mesons at the Tevatron
V. Krey, K. R. S. Balaji
In the framework of NRQCD and parton model, we estimate in detail,the production cross section for polarized J/psi from B meson decays. In order to contrast with data, we also take…
Neutrino magnetic moment, large extra dimensions and high energy cosmic neutrino spectra
K. R. S. Balaji, A. Dighe, R. N. Mohapatra
We point out that the presence of bulk neutrinos in models with large extra spatial dimensions can lead to observable flavour specific deformations in the spectra of extreme high e…
Leptogenesis and low energy observables in left-right symmetric models
K. R. S. Balaji, W. Rodejohann
In the context of left-right symmetric models we study the connection of leptogenesis and low energy parameters such as neutrinoless double beta decay and leptonic CP violation. Up…
Discussion on a possible neutrino detector located in India
M. V. N. Murthy, U. A. Yajnik
We have identified some important and worthwhile physics opportunitites with a possible neutrino detector located in India. Particular emphasis is placed on the geographical advant…
Revisiting pseudo-Dirac neutrinos
K. R. S. Balaji, Anna Kalliomaki, Jukka Maalampi
We study the pseudo-Dirac mixing of left and right-handed neutrinos in the case where the Majorana masses M_L and M_R are small when compared with the Dirac mass, M_D. The light Ma…
Large Lepton Mixings Induced by Sterile Neutrino
K. R. S. Balaji, A. Pérez-Lorenzana, A. Yu. Smirnov
We assume that the mass matrix of active neutrinos has hierarchical form with small mixings, similar to quark mass matrix. We show that the large mixings between and as…
