Yukawa's of light stringy states | | Pascal Anastasopoulos

29 Sep 2016 | | Abstract: | Light massive string states can appear at D-brane intersections with small
angles. We compute tri-linear Yukawa couplings of such open-string states to
massless ones and to one another. Due to ambiguities in the normalisation of
the vertex operators, that involve twist fields, we proceed via factorization
of appropriate scattering amplitudes. Some peculiar features are observed that
may lead to interesting signatures at colliders in the future. | | Source: | arXiv, 1609.9299 | | Services: | Forum | Review | PDF | Favorites | |
