SU(5) grand unification on a domain-wall brane from an E_6-invariant action
Aharon Davidson, Damien P. George, Archil Kobakhidze +2
An SU(5) grand unification scheme for effective 3+1-dimensional fields dynamically localised on a domain-wall brane is constructed. This is achieved through the confluence of the c…
Existence and Stability of Non-Trivial Scalar Field Configurations in Orbifolded Extra Dimensions
Manuel Toharia, Mark Trodden
We consider the existence and stability of static configurations of a scalar field in a five dimensional spacetime in which the extra spatial dimension is compactified on an $S^1/Z…
Metastable Kinks in the Orbifold
Manuel Toharia, Mark Trodden
We consider static configurations of bulk scalar fields in extra dimensional models in which the fifth dimension is an orbifold. There may exist a finite number of such c…
LHC Signals for Warped Electroweak Neutral Gauge Bosons
Kaustubh Agashe, Hooman Davoudiasl, Shrihari Gopalakrishna +5
We study signals at the Large Hadron Collider (LHC) for Kaluza-Klein (KK) excitations of the electroweak gauge bosons in the framework with the Standard Model (SM) gauge and fermio…
Low energy scattering with a nontrivial pion
Amir H. Fariborz, Renata Jora, Joseph Schechter
An earlier calculation in a generalized linear sigma model showed that the well-known current algebra formula for low energy pion pion scattering held even though the massless Namb…
Two chiral nonet model with massless quarks
Amir H. Fariborz, Renata Jora, Joseph Schechter
We present a detailed study of a linear sigma model containing one chiral nonet transforming under U(1) as a quark-antiquark composite and another chiral nonet transforming as…
