Furthermore, new chiral non-invariant counterterms involving the Higgs particle and pions have been found in our perturbative analysis. These findings extend to the realm of the

We consider the general chiral effective action which parametrizes the nonlinear realization of the spontaneous breaking of the electroweak symmetry with a light Higgs boson and

In particular, we will study self-sorting (Figure 114) and chiral induction events at both the level of the cyclic tetramer and the supramolecular polymer. Our

As a summary, we have analyzed the baryonic low energy spectrum with a potential model that includes, besides the usual one-gluon exchange, pion and sigma exchanges be- tween quarks

The point is that the sw determinant is exactly gauge invariant and we know how to non-perturbatively restore the global chiral symmetry broken by the standard Wilson term on a

In this paper we reconsider the simplest of these theories, the gauged non-linear chiral model defined on a lattice, and argue that its continuum limit within a Higgs phase, if

By keeping an active charm quark and employing a lattice for- mulation which preserves chiral symmetry, power-divergent subtractions of the relevant operators can be avoided, and

The cornerstone of the suspicion of a chiral phase transition is the singular behavior of the quark condensate < q ¯ q >, since this expectation value is an order parameter
