RNS model from a new angle for strings charged under the Maximal Gauge Symmetry of the Standard model
J. S. Bhattacharyya
We consider the RNS model from a new angle. The longitudinal and time components of the world-sheet fermions add a charge to a state. Unlike the gauginos, the ground state f…
A Critical String Theory in (3+1)+4 Dimensions for the Standard Model with Three Generations of Fermions and Ultra-Heavy Sterile Right-Handed Neutrinos
J. S. Bhattacharyya
Redefining the vacuum state of a free two-fold covariant supersymmetric string action as the one with all the excited states of world-sheet fermions occupied, makes the theor…
Two signs of a Schwinger term in a commutator of fermionic currents
J. S. Bhattacharyya
We consider central extensions of two dimensional abelian current algebra and Virasoro algebra and see that the sign of the Schwinger term changes if we arrange the Fourier modes o…
A Critical String Theory in 3+1 Dimensions
J. S. Bhattacharyya, Gautam Bhattacharya
Redefining the vacuum state of a free twofold N=1 covariant supersymmetric string action as the one with all the world sheet fermionic excited states occupied, makes the theory ano…
Neutrino Oscillation as Coupled vibration
Jyotisekhar Bhattacharyya, Satyabrata Biswas
Neutrino oscillation is visualized as coupled vibrations. Unlike existing models describing neutrino oscillations, our model involving a single fundamental mass parameter and f…
