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...
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...
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...
D. R. Tovey, P. Gondolo, Y. Ramachers, L. Roszkowski
A method is proposed for extracting limits on spin-dependent WIMP-nucleon interaction cross sections from direct detection dark matter experiments. The new method has the advantage that the limits on...
Cerdeno, D.G., Choi, Ki-Young, Jedamzik, K., Roszkowski, L.
In the framework of the Constrained MSSM we re--examine the gravitino as the lightest superpartner and a candidate for cold dark matter in the Universe. Unlike in other recent studies, we include...
On the detectability of the CMSSM light Higgs boson at the Tevatron (2006)
We examine the prospects of detecting the light Higgs scalar h^0 of the Constrained MSSM at the Tevatron. To this end we explore large ranges of the CMSSM parameter space with mu>0 using a Markov...
Solving the Cosmic Lithium Problems with Gravitino Dark Matter in the CMSSM (2006)
Standard Big Bang nucleosynthesis at baryonic density as inferred by WMAP implies a primordial Li7 abundance factor of two to three larger than that inferred by observations of low--metallicity halo...
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...
Signatures of Axinos and Gravitinos at Colliders (2005)
Brandenburg, A, Covi, L, Hamaguchi, K, Roszkowski, L, Steffen, F D
The axino and the gravitino are well-motivated candidates for the lightest supersymmetric particle (LSP) and also for cold dark matter in the Universe. Assuming that a charged slepton is the...

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 $SO_{10}$...

SUPERSYMMETRIC PHENOMENOLOGY IN THE LIGHT OF GRAND UNIFICATION (1995)
I review some aspects of supersymmetric grand unification and emphasize a recent development in the area of gauge coupling unification.
Reconciling Supersymmetric Grand Unification with $\alpha_s(m_Z)\approx 0.11$ (1995)
We argue that supersymmetric grand unification of gauge couplings is not incompatible with small $\alpha_s$, even without large GUT-scale corrections, if one relaxes a usual universal gaugino mass...
Roberts, R. G., Roszkowski, L.
We examine various predictions of the minimal supersymmetric standard model coupled to minimal supergravity. The model is characterised by a small set of parameters at the unification scale. The...
