DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/13/">Ad
 S and dS vacua from torsion and non-BPS states</a>\nby Oscar Loaiza-Brito 
 (Guanajuato U.) as part of AnLy Strings and Fields online seminars\n\n\nAb
 stract\nWe look for minimal conditions to construct stable Anti de Sitter 
 and de Sitter vacua from type IIB String theory compactification on Kähle
 r manifolds with torsion in the presence of O3-planes. This allows contrib
 utions to the scalar potential from the five-form flux and from D5-branes 
 wrapping torsional cycles -interpreted as non-BPS states carrying discrete
  Z_2 charge and classified by K-theory- which in turn leads to the constru
 ction of AdS and dS vacua respectively. We shall discuss some constraints 
 on the configuration as well as possible sources of instabilities.\n
