Strong CP: No Problem
P. Mitra
Detailed analysis shows that the phase of a complex mass term of a quark does not violate CP, while the QCD vacuum angle can naturally be set equal to zero. There is no strong CP p…
Chiral phase in fermionic measure and the resolution of the strong CP problem
P. Mitra
The fermionic measure in the functional integral of a gauge theory suffers from an ambiguity in the form of a chiral phase. By fixing it, one is led once again to the conclusion th…
Understanding CP violation in lattice QCD
P. Mitra
It is pointed out that any CP violation which may be found in lattice QCD with a chiral phase in the fermion mass term cannot be relevant for the continuum theory. CP is classicall…
Quantization of Gauge Theories with Anomalies
P. Mitra
In this talk, we briefly review the basic concepts of anomalous gauge theories. It has been known for some time how theories with local anomalies can be handled. Recently it has be…
Exclusion statistics and many-particle states
P. Mitra
The thermodynamic distribution function for exclusion statistics is derived. Creation and annihilation operators for particles obeying such statistics are discussed. A connection w…
