Self-gravitating non-abelian kinks as brane worlds
Alejandra Melfo, Roger Naranjo, Nelson Pantoja +2
We address the properties of self-gravitating domain walls arising from the breaking of an SU(N) x Z_2- symmetric theory. In the particular case of N=5, we find that the two classe…
Close to the edge: hierarchy in a double braneworld
Rommel Guerrero, Alejandra Melfo, Nelson Pantoja +1
We show that the hierarchy between the Planck and the weak scales can follow from the tendency of gravitons and fermions to localize at different edges of a thick double wall embed…
Fermion localization on thick branes
Alejandra Melfo, Nelson Pantoja, Jose David Tempo
We consider chiral fermion confinement in scalar thick branes, which are known to localize gravity, coupled through a Yukawa term. The conditions for the confinement and their beha…
