This talk proposes a direct link between the hierarchy problem and Weakly Interacting Massive Particles (WIMPs): we suggest that the small mass of the Higgs boson arises from being dynamically driven to the scale of the WIMP. Such a special electroweak vacuum is singled out by lying close to the critical boundary of a phase transition, as recently explored in a new class of cosmological...
I will talk about dispersion relations (analog of Kramers-Kronig relations) for tidal Love number of weakly gravitating compact objects.
The holographic principle suggests that quantum gravity can be described by an equivalent lower-dimensional field theory. While this idea is well-established in anti–de Sitter space, extending it to more realistic settings remains an open challenge. This talk presents recent progress toward a flat space hologram, where scattering amplitudes are expressed as correlators at null infinity. I will...
Las teorías finitas de gran unificación son teorías del campo supersimétricas que están libres de divergencias en el UV, esta libertad se codifica en función de sus RGE's, exhibiendo del mismo modo una invarianza ante transformaciones conformes. En este trabajo se estudia el rompimiento de supersimetría en este tipo de modelos desde dos puntos de vista; el primero es un estudio teórico del...
