Renormalizing a BRST-invariant composite operator of mass dimension 2 in Yang-Mills theory
K. -I. Kondo, T. Murakami, T. Shinohara +1
We discuss the renormalization of a BRST and anti-BRST invariant composite operator of mass dimension 2 in Yang-Mills theory with the general BRST and anti-BRST invariant gauge fix…
A confining string theory derived from QCD
Kei-Ichi Kondo
We report an attempt of deriving a string representation of QCD based on a novel vacuum condensate of mass dimension 2.
Vacuum condensate of mass dimension 2 as the origin of mass gap and quark confinement
Kei-Ichi Kondo
We propose a vacuum condensate of mass dimension 2 consisting of gluons and ghosts in the framework of the manifestly covariant gauge fixing of the SU(N) Yang-Mills theory. This qu…
The Most General and Renormalizable Maximal Abelian Gauge
T. Shinohara, T. Imai, K. -I. Kondo
We construct the most general gauge fixing and the associated Faddeev-Popov ghost term for the SU(2) Yang-Mills theory, which leaves the global U(1) gauge symmetry intact (i.e., th…
Renormalizable Abelian-projected effective gauge theory derived from Quantum Chromodynamics II
T. Shinohara
In the previous paper\cite{KS00b}, we derived the Abelian projected effective gauge theory as a low energy effective theory of the SU(N) Yang-Mills theory by adopting the maximal A…
Relations between Non-Commutative and Commutative Spacetime
Ken-Ichi Tezuka
Spacetime non-commutativity appears in string theory. In this paper, the non-commutativity in string theory is reviewed. At first we review that a Dp-brane is equivalent to a confi…
