</svg> Supergravity Vacua of Type II Superstrings 本地全文： 下载 作者： Massimo Bianchi 期刊名称： Advances in High Energy Physics 印刷版ISSN： 1687-7357 电子版ISSN： 1687-7365 出版年度： 2011 卷号： 2011 DOI： 10.1155/2011/479038 出版社： Hindawi Publishing Corporation 摘要： We compute one-loop threshold corrections to ℛ4 terms in 𝒩=5,6 supergravity vacua of Type II superstrings. We then discuss nonperturbative corrections generated by asymmetric D-brane instantons. Finally we derive generating functions for MHV amplitudes at tree level in 𝒩=5,6 supergravities.
