Baryon Inhomogeneity Generation in the Quark-Gluon Plasma Phase
Biswanath Layek, Ananta P. Mishra, Ajit M. Srivastava +1
We discuss the possibility of generation of baryon inhomogeneities in a quark-gluon plasma phase due to moving Z(3) interfaces. By modeling the dependence of effective mass of the…
Iso-curvature fluctuations through axion trapping by cosmic string wakes
Biswanath Layek
We consider wake-like density fluctuations produced by cosmic strings at the quark-hadron transition in the early universe. We show that low momentum axions which are produced thro…
Strings with a confining core in a Quark-Gluon Plasma
Biswanath Layek, Ananta P. Mishra, Ajit M. Srivastava
We consider the intersection of N different interfaces interpolating between different vacua of an SU(N) gauge theory using the Polyakov loop order parameter. Topological arg…
Excited hadrons as a signal for quark-gluon plasma formation
Biswanath Layek, Ajit M. Srivastava, Soma Sanyal
At the quark-hadron transition, when quarks get confined to hadrons, certain orbitally excited states, namely those which have excitation energies above the respective stat…
Working Group Report: Neutrino and Astroparticle Physics
Srubabati Goswami, Raghavan Rangarajan, K. Agashe +37
This is the report of neutrino and astroparticle physics working group at WHEPP-8. We present the discussions carried out during the workshop on selected topics in the above fields…
Skyrmion formation in 1+1 dimensions with chemical potential
V. Sunil Kumar, Biswanath Layek, Soma Sanyal +2
Formation of topological objects during phase transitions has been discussed extensively in literature. In all these discussions defects and anti-defects form with equal probabilit…
Baryon inhomogeneity generation via cosmic strings at QCD scale and its effects on nucleosynthesis
Biswanath Layek, Soma Sanyal, Ajit M. Srivastava
We have earlier shown that cosmic strings moving through the plasma at the time of a first order quark-hadron transition in the early universe can generate large scale baryon inhom…
Cosmic string induced sheet like baryon inhomogeneities at quark-hadron transition
Biswanath Layek, Soma Sanyal, Ajit M. Srivastava
Cosmic strings moving through matter produce wakes where density is higher than the background density. We investigate the effects of such wakes occurring at the time of a first or…
