We consider a general situation where a charged massive scalar field φ(x) at finite temperature interacts with a magnetic flux cosmic string. We determine a general expression for the Euclidean thermal ∗electronic address: [email protected]

We study a dynamically broken U (1) L gauge theory endowed with a composite scalar doublet (one scalar and one pseudoscalar); its Lagrangian only differs from that of an abelian 'Standard Model' by the addition of a derivative coupling between a Wess-Zumino field, linked to the previous scalars, and the fermionic current. Yet, in the Feynman path integral, the non independence of the fermionic ...
