Anomalies and bordism of non-supersymmetric heterotic strings
Time: 12:00 pm - 1:15 pm
Place: Van Vleck B223 (Note Special Room)
Speaker: Miguel Montero, Instituto de Física Teórica, Madrid
Abstract: There are three tachyon-free non-supersymmetric string theories in ten dimensions where anomalies cancel by a non-supersymmetric version of the Green-Schwarz mechanism. However, these theories have not been shown to be free of global anomalies. I will fill this gap by studying these anomalies with cobordism theory; as a byproduct we will compute bordism groups of these non-susy strings, which may be useful to the construction of new charged branes in this theory using the cobordism conjecture.
