The AdS/CFT/Unparticle Correspondence (2008)
Cacciapaglia, Giacomo, Marandella, Guido, Terning, John
We examine the correspondence between the anti-de Sitter (AdS) description of conformal field theories (CFTs) and the unparticle description of CFTs. We show how unparticle actions are equivalent to...
Cacciapaglia, Giacomo, Marandella, Guido, Terning, John
We examine a scenario where the new physics at the LHC includes an approximate conformal field theory, where some of the degrees of freedom (aka "unparticles") carry a color charge. We present a...
Mass Determination in SUSY-like Events with Missing Energy (2007)
Cheng, Hsin-Chia, Gunion, John F., Han, Zhenyu, Marandella, Guido, McElrath, Bob
We describe a kinematic method which is capable of determining the overall mass scale in SUSY-like events at a hadron collider with two missing (dark matter) particles. We focus on the kinematic...
Cacciapaglia, Giacomo, Csáki, Csaba, Marandella, Guido, Terning, John
We present a class of models that contains Randall-Sundrum and Higgsless models as limiting cases. Over a wide range of the parameter space WW scattering is mainly unitarized by Kaluza-Klein partners...
A New Custodian for a Realistic Higgsless Model (2006)
Cacciapaglia, Giacomo, Csáki, Csaba, Marandella, Guido, Terning, John
We present an example of a realistic Higgsless model that makes use of alternative $SU(2)_R$ assignments for the top and bottom quarks recently proposed by Agashe et al. which results in an enhanced...
ElectroWeak precision data: the minimal set of parameters (2006)
We show how precision electroweak data, assuming CP conservation and flavor universality, despite being sensitive to 20 dimension 6 operators, constrain severely only 9 combinations of them. We...
Csaki, Csaba, Marandella, Guido, Shirman, Yuri, Strumia, Alessandro
Supersymmetry combined with little-Higgs can render the Higgs vev super-little, providing models of electroweak symmetry breaking free from fine-tunings. We discuss the difficulties that arise in...
Supersymmetry and precision data after LEP2 (2005)
Marandella, Guido, Schappacher, Christian, Strumia, Alessandro
We study one loop supersymmetric corrections to precision observables. Adding LEP2 e ebar --> f fbar cross sections to the data-set removes previous hints for SUSY and the resulting constraints are...
Little-Higgs corrections to precision data after LEP2 (2005)
Marandella, Guido, Schappacher, Christian, Strumia, Alessandro
We reconsider little-Higgs corrections to precision data. In five models with global symmetries SU(5), SU(6), SO(9) corrections are (although not explicitly) of `universal' type. We get simple...
Marandella, Guido, Papucci, Michele
In models with supersymmetry breaking by boundary conditions on an extra dimension it is possible to relate in a quantitative natural way the Fermi scale to the size of the extra dimension. We...
Sterile neutrinos: from cosmology to experiments (2004)
We analyze the oscillation signals generated by one extra sterile neutrino. We fully take into account the effects of the established oscillations among active neutrinos. We analyze the effects in...
Probing oscillations into sterile neutrinos with cosmology, astrophysics and experiments (2004)
Cirelli, Marco, Marandella, Guido, Strumia, Alessandro, Vissani, Francesco
We perform a thorough analysis of oscillation signals generated by one extra sterile neutrino, extending previous analyses done in simple limiting cases and including the effects of established...
The Higgs mass as a function of the compactification scale (2003)
Barbieri, Riccardo, Marandella, Guido, Papucci, Michele
We calculate to a few percent precision the Higgs potential in a model with supersymmetry broken by boundary conditions on an extra-dimension, compactified to a segment of length $L$, and a top quark...
Radiative Electroweak Symmetry Breaking from a Quasi-Localized Top Quark (2002)
Barbieri, Riccardo, Hall, Lawrence J., Marandella, Guido, Nomura, Yasunori, Okui, Takemichi, Oliver, Steven J., ...
We consider 5D supersymmetric SU(3) x SU(2) x U(1) theories compactified at the TeV scale on S^1/Z_2 with supersymmetry broken by boundary conditions. Localizing the top quark at a boundary of a...
Breaking the electroweak symmetry and supersymmetry by a compact extra dimension (2002)
Barbieri, Riccardo, Marandella, Guido, Papucci, Michele
We revisit in some more detail a recent specific proposal for the breaking of the electroweak symmetry and of supersymmetry by a compact extra dimension. Possible mass terms for the Higgs and the...
