String and Brane Tensions as Dynamical Degrees of Freedom
Abstract
We discuss a new class of string and pbrane models where the string/brane tension appears as an additional dynamical degree of freedom instead of being introduced by hand as an ad hoc dimensionfull scale. The latter property turns out to have a significant impact on the string/brane dynamics. The dynamical tension obeys Maxwell (or YangMills) equations of motion (in the string case) or their rank p gauge theory analogues (in the pbrane case), which in particular triggers a simple classical mechanism of ("color") charge confinement.
