Misaligned SUSY and the effective central charge criterion
In this talk I will present a criterion from which it is possible to see whether tachyons are present in the tree level spectrum for closed string models. I will review the ideas that have come out since the mid 90's to clarify their role and their meaning before presenting a general argument, through which the criterion is built, and providing some examples. Afterwards I will give some hints on how the construction can be adapted in the case of open strings.
