The Energy Density in the Maxwell-Chern-Simons Theory
Denne Wesolowski, Yutaka Hosotani, Sumantra Chakravarty
A two-dimensional nonrelativistic fermion system coupled to both electromagnetic gauge fields and Chern-Simons gauge fields is analysed. Polarization tensors relevant in the quantu…
Final-state ππinteractions in Υ(3S)\rightarrowΥ(1S)ππ
Sumantra Chakravarty, Sun Myong Kim, Pyungwon Ko
The spectrum and various angular distributions in $\upss$ are studied including the effects of the phase shift in the channel using the lowest order amplitude…
Is Upsilon(3S) a pure S-wave?
Sumantra Chakravarty, Sun Myong Kim, Pyungwon Ko
Assuming the QCD multipole expansion is applicable to hadronic transitions of Upsilon(3S) into lower level bottomonia, we consider the possibility that Upsilon(3S) has a D-wave com…
Vortex Production in a First Order Phase-Transition at Finite Temperature
Sumantra Chakravarty, Ajit Mohan Srivastava
We simulate the production of vortices in a first order phase transition at finite temperature. The transition is carried out by randomly nucleating critical bubbles and the effect…
