It is known that not every effective field theory could be embedded in quantum gravity, but only those which are consistent with the QG conjectures. Does these constraints have an impact in low energy physics? Recently, Ooguri and Vafa argued using a strong approach of the Weak Gravity Conjecture that non-supersymmetric stable AdS vacua are incompatible with quantum gravity. It is also known...
We explore the possibility of dynamically generating bulk fermion masses with an odd bulk scalar in warped extra dimensions. The odd bulk scalar acquires vacuum expectation value (VEV) along the extra-dimension and its Yukawa interactions with bulk fermions generate their bulk masses. The zero-mode localization of fermions along the warped extra dimension naturally explain the observed flavor...
Massive neutrinos and baryon feedback both suppress the matter power spectrum at small scales and are therefore expected to be degenerate with each other. I will show that this degeneracy is not perfect and can indeed be broken by performing tomography on the cold dark matter and shear power spectra. Neutrino effects and non-linearities are included through fitting functions to N-body...
The best strategy for indirect detection of dark matter depends entirely on its annihilation processes. In this work we discuss a model independent probe for dark matter annihilations into right-handed neutrinos in the GeV-TeV mass range, using dwarf spheroidal galaxies and the galactic center observations performed by Fermi-LAT and H.E.S.S., respectively. We exclude the thermal annihilation...
