Title: Higgs-confinement phase transition in 2+1 D abelian superfluids.

Abstract : I discuss the conditions under which Higgs and confining regimes in a gauge theory can be sharply distinguished. It is widely believed that these regimes are smoothly connected unless they are distinguished by the realization of global symmetries. However, we show that when a U(1) global symmetry is spontaneously broken in both the confining and Higgs regimes, there is a novel order parameter which can detect certain Higgs-confinement phase transitions. This result is explained in the context of certain tractable gauge theories in three spacetime dimensions.
