A Calogero-Sutherland Type Model For Branched Polymers
Dileep P. Jatkar, Avinash Khare
We show that a Calogero-Sutherland type model with anharmonic interactions of fourth and sixth orders leads to the matrix model corresponding to the branched polymers. We also show…
Ultrahigh-Energy Neutrino Interactions
Raj Gandhi, Chris Quigg, Mary Hall Reno +1
Cross sections for the interactions of ultrahigh-energy neutrinos with nucleons are evaluated in light of new information about nucleon structure functions. For --eV neutr…
T-Duality of p-Branes
Ashoke Sen
We investigate possible existence of duality symmetries which exchange the Kaluza-Klein modes with the wrapping modes of a BPS saturated -brane on a torus. Assuming the validity…
Dyonic Black Hole in Heterotic String Theory
Dileep P. Jatkar, Sudipta Mukherji, Sudhakar Panda
We study some features of dyonic Black hole solution in heterotic string theory on a six torus. This solution has 58 parameters. Of these, 28 parameters denote the electric charge…
Dualities in Five Dimensions and Charged String Solutions
Supriya Kar, Jnanadeva Maharana, Sudhakar Panda
We consider an eleven dimensional supergravity compactified on and show that the resulting five dimensional theory has identical massless states as that of heterotic…
Notes on a singular Landau-Ginzburg family
Debashis Ghoshal
We study some properties of a singular Landau-Ginzburg family characterized by the multi-variable superpotential . We will…
