Stability of the Magnetic Monopole Condensate in three- and four-colour QCD

TL;DR

This paper argues that the ground state of three- and four-color QCD contains a monopole condensate, which is essential for the dual Meissner effect and confinement, and demonstrates its stability by showing it gives off-diagonal gluons an effective mass.

Contribution

It provides a theoretical argument supporting the stability of monopole condensates in multi-color QCD, crucial for understanding confinement mechanisms.

Findings

Monopole condensate is present in three- and four-color QCD ground states.

The condensate stabilizes the ground state by giving off-diagonal gluons an effective mass.

Supports the dual Meissner effect as the confinement mechanism.

Abstract

It is argued that the ground state of three- and four-colour QCD contains a monopole condensate, necessary for the dual Meissner effect to be the mechanism of confinement, and support its stability on the grounds that it gives the off-diagonal gluons an effective mass sufficient to remove the unstable ground state mode.
