We construct a q-deformed algebra of creation and destruction operators with ordered indices in which the deformation parameter is complex. Its consequences are studied and its relation to “fractional” statistics is pointed out.

We construct the quantum field theory of particles obeying new kinds of quantum statistics, called orthofermi and orthobose statistics. For the orthofermions (orthobosons), the wave function is antisymmetric (symmetric) ...

Two approaches have been used so far to understand the observed hadron spectrum: a) to regard any observed hadron as a composite (bound or resonant) formed by forces between other observed hadrons, and b) to consider the ...

This is an elementary review of the history and physics of neutrinos. The story of the discovery of neutrino mass through neutrino oscillations is described in some detail. Experiments on solar neutrinos and atmospheric ...

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 and also indicate progress made subsequently. ...
