Electromagnetism in Nonleptonic Weak Interactions *

We construct a low-energy effective field theory that permits the complete treatment of isospin-breaking effects in nonleptonic weak interactions to next-to-leading order. To this end, we enlarge the chiral Lagrangian describing strong and ∆S = 1 weak interactions by including electromagnetic terms with the photon as additional dynamical degree of freedom. The complete and minimal list of local...

Multisphalerons in the Weak Interactions

We construct multisphaleron solutions in the weak interactions. The multisphaleron solutions carry Chern-Simons charge n/2, where n is an integer. The well-known sphaleron has n = 1 and is spherically symmetric for vanishing mixing angle. In contrast the multisphalerons with n > 1 are only axially symmetric, even for vanishing mixing angle. The greater n, the stronger the energy density deforms...

Aspects of weak interactions

Weak interactions, such as those non-covalent interactions that occur in biological systems, are less well characterised than their strong, covalent counterparts. Here, we discuss associations between two or more molecules and consider the effect of interactions with solvent molecules (particularly water) and changes in the internal structure of the associating molecules on binding. We go on to...
