Bethe Colloquium by Luis Ibáñez

January 2018
Luis Ibáñez

The first Bethe Colloquium in 2018 will take place on Thursday, January 11th (4:15 pm) in Hörsaal I:

  • Luis Ibáñez (IFT, UAM Madrid)
  • Swampland Constraints on SM Physics and the Cosmological Constant
  • Hörsaal I, Physikalisches Institut

Abstract: The swampland is the space of field theories which cannot be embedded into a consistent theory of quantum gravity. Recently substantial effort has been dedicated to understand this swampland in terms of black-hole physics and string theory. One of the leading ideas is the weak gravity conjecture and different generalisations and extensions. In one of them Ooguri and Vafa have conjectured that no consistent theory of quantum gravity can contain AdS non-SUSY, stable minima. Appplying this criterium to the SM and its compactifications to 3 and 2 dimensions, one can derive strong con-straints on neutrino masses and the cosmological constant. The lightest neutrino mass is predicted to be lighter than the cosmological constant scale. This bound, for fixed Yukawa couplings, implies that values of the Electro-Weak scale above 1 TeV would be in the swampland and would not count as possible consistent theories. This would bring a new perspective into the issue of the EW hierarchy.

May 2018
Planck2013

The 21st International Conference "Planck 2018 - From the Planck Scale to the Electroweak scale" will take place from May 21st to May 25th, 2018, at Universität Bonn.

The conference is organized by the Bethe Center for Theoretical Physics (bctp) of the Universität Bonn for a network consisting of several European research groups: Bonn, CERN, Trieste, Madrid, Oxford, Padua, Paris and Warsaw.
More information as well as the registration form are available here.

There is an accompanying Bethe Forum Program in the week following the conference.
