Double Field Theory and alpha prime corrections
Eric Lescano
IAFE-CONICET-UBA, Buenos Aires, Argentina
Datum: petak, 23. ožujka 2018.
Vrijeme: 15 sati c.t.
Mjesto: IRB, predavaona I krila
Sažetak:
String Theory (ST) is an attempt to make General Relativity and
Quantum mechanics live together. The universal massless low energy
effective action of String Theory coincides with a supergravity
action, a particle theory where the fundamental fields involve a
metric, a scalar field and a two-form. A difficult task in ST is to
find higher-order derivative corrections (alpha prime corrections) to
this action that respect the symmetries of ST. On the other hand,
Double Field Theory (DFT) is a proposal to incorporate T-duality, a
distinctive symmetry of string theory, as a symmetry of a field theory
defined on a double configuration space. The idea of this talk is
introduce some basics ideas of supergravity and DFT, and show how the
latter could be a powerful tool to find alpha prime corrections.
