Electromagnetic signals from bare strange stars
Massimo Mannarelli, Giulia Pagliaroli, Alessandro Parisi +1
The crystalline color superconducting phase is believed to be the ground state of deconfined quark matter for sufficiently large values of the strange quark mass. This phase has th…
Soft SUSY breaking contributions to proton decay
Zurab Berezhiani, Fabrizio Nesti, Luigi Pilo
We show that in supersymmetric grand unified theories new effective D=4 and D=5 operators for proton decay are induced by soft SUSY-breaking terms, when heavy GUT gauge bosons are…
Towards a Realistic Model of Higgsless Electroweak Symmetry Breaking
Csaba Csaki, Christophe Grojean, Luigi Pilo +1
We present a 5D gauge theory in warped space based on a bulk SU(2)_L x SU(2)_R x U(1)_(B-L) gauge group where the gauge symmetry is broken by boundary conditions. The symmetry brea…
Gauge Theories on an Interval: Unitarity without a Higgs
C. Csaki, C. Grojean, H. Murayama +2
We consider extra dimensional gauge theories on an interval. We first review the derivation of the consistent boundary conditions (BC's) from the action principle. These BC's inclu…
Supersymmetry breaking with quasi-localized fields in orbifold field theories
G. V. Gersdorff, L. Pilo, M. Quiros +2
We study the Scherk-Schwarz supersymmetry breaking in five-dimensional orbifold theories with five-dimensional fields which are not strictly localized on the boundaries (quasi-loca…
Gauge Quintessence
L. Pilo, D. A. J. Rayner, A. Riotto
We discuss a new model of quintessence in which the quintessence field is identified with the extra-component of a gauge field in a compactified five-dimensional theory. We show th…
Running and Matching from 5 to 4 Dimensions
R. Contino, L. Pilo, R. Rattazzi +1
We study 5 dimensional grand-unified theories in an orbifold geometry by the method of effective field theory: we match the low and high energy theories by integrating out at 1-loo…
A Note on Regularization methods in Kaluza-Klein Theories
Roberto Contino, Luigi Pilo
We comment on the presence of power-like divergences in Kaluza-Klein theories with supersymmetry breaking a là Scherk-Schwarz. By introducing a SUSY preserving regulator, we show t…
Graviton loops and brane observables
R. Contino, L. Pilo, R. Rattazzi +1
We discuss how to consistently perform effective Lagrangian computations in quantum gravity with branes in compact extra dimensions. A reparametrization invariant and infrared fini…
The Non-commutative Brane World
Luigi Pilo, Antonio Riotto
We propose a new higher-dimensional mechanism to localize scalar fields as well as fermionic and gauge fields. The underlying theory is a six-dimensional non-commutative field theo…
