Efficient reconstruction of CMSSM parameters from LHC data - A case study (2009)
Roszkowski, L., De Austri, R. Ruiz, Trotta, R.
We present an efficient method of reconstructing the parameters of the Constrained MSSM from assumed future LHC data, applied both on their own right and in combination with the cosmological...
Prospects for dark matter detection with IceCube in the context of the CMSSM (2009)
Trotta, R., De Austri, R. Ruiz
We study in detail the ability of the nominal configuration of the IceCube neutrino telescope (with 80 strings) to probe the parameter space of the Constrained MSSM (CMSSM) favoured by current...
Neutrino Physics and Spontaneous CP Violation in the $\mu\nu$SSM (2009)
Fidalgo, J., Lopez-Fogliani, D. E., Munoz, C., De Austri, R. Ruiz
The $\mu\nu$SSM provides a solution to the $\mu$ problem of the MSSM and explains the origin of neutrino masses by simply using right-handed neutrino superfields. We have completed the analysis of...
Are BR(b->s gamma) and (g-2)_muon consistent within the Constrained MSSM? (2009)
Feroz, F., Hobson, M. P., Roszkowski, L., De Austri, R. Ruiz, Trotta, R.
We employ two different statistical tests to examine whether, in the framework of the Constrained MSSM, the experimentally determined values of BR(b->s gamma) and the anomalous magnetic moment of the...
Some novel features of the Non-Universal Higgs Model (2009)
Roszkowski, L., De Austri, R. Ruiz, Trotta, R., Tsai, Y. -L. S., Varley, T. A.
We examine the Non-Universal Higgs Model (NUHM) with the help of a Markov Chain Monte Carlo scanning technique and Bayesian statistics. The method allows us to reveal more fully the remarkably rich...
Bayesian approach and Naturalness in MSSM analyses for the LHC (2008)
Cabrera, M. E., Casas, J. A., De Austri, R. Ruiz
The start of LHC has motivated an effort to determine the relative probability of the different regions of the MSSM parameter space, taking into account the present, theoretical and experimental,...
The impact of priors and observables on parameter inferences in the Constrained MSSM (2008)
Trotta, R., Feroz, F., Hobson, M. P., Roszkowski, L., De Austri, R. Ruiz
We use a newly released version of the SuperBayeS code to analyze the impact of the choice of priors and the influence of various constraints on the statistical conclusions for the preferred values...
Flat Tree-level Inflationary Potentials in Light of CMB and LSS Data (2007)
Ballesteros, G, Casas, J A, Espinosa, J R, De Austri, R Ruiz, Trotta, R
We use cosmic microwave background and large scale structure data to test a broad and physically well-motivated class of inflationary models: those with flat tree-level potentials (typical in...
Flat Tree-level Inflationary Potentials in Light of CMB and LSS Data (2007)
Ballesteros, G., Casas, J. A., Espinosa, J. R., De Austri, R. Ruiz, Trotta, R.
We use cosmic microwave background and large scale structure data to test a broad and physically well-motivated class of inflationary models: those with flat tree-level potentials (typical in...
Dark Matter And $B_s \to \mu^+ \mu^-$ With Minimal $SO_{10}$ Soft SUSY Breaking II (2005)
Dermisek, R., Raby, S., Roszkowski, L., De Austri, R. Ruiz
We update and extend to larger masses our previous analysis of the MSSM with minimal $SO_{10}$ [MSO$_{10}$SM] soft SUSY breaking boundary conditions. We find a well--defined, narrow region of...
Lazarides, G., De Austri, R. Ruiz, Trotta, R.
We consider a supersymmetric grand unified model which naturally solves the strong CP and mu problems via a Peccei-Quinn symmetry and leads to the standard realization of hybrid inflation. We show...
Dark Matter And $B_s \to \mu^+ \mu^-$ With Minimal $SO_{10}$ Soft SUSY Breaking (2003)
Dermisek, R., Raby, S., Roszkowski, L., De Austri, R. Ruiz
CMSSM boundary conditions are usually used when calculating cosmological dark matter densities. In this paper we calculate the cosmological density of dark matter in the MSSM using minimal $SO_{10}$...
