Phenomenological Indications of the Scale of Supersymmetry
/ Ellis, John R. (CERN) ; Heinemeyer, Sven (Zaragoza U.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.) ; Weiglein, Georg (Durham U., IPPP)
Electroweak precision measurements can provide indirect information about the possible scale of supersymmetry already at the present level of accuracy. We update the present-day sensitivities of precision data using the new experimental top-quark mass, m_t = 172.7 \pm 2.9 GeV, within the constrained minimal supersymmetric extension of the Standard Model (CMSSM), in which there are three independent soft supersymmetry-breaking parameters m_{1/2}, m_0 and A_0.

Indirect Sensitivities to the Scale of Supersymmetry
/ Ellis, John R. (CERN) ; Heinemeyer, Sven (CERN) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.) ; Weiglein, Georg (Durham U., IPPP)
Precision measurements, now and at a future linear electron-positron collider (ILC), can provide indirect information about the possible scale of supersymmetry. We illustrate the present-day and possible future ILC sensitivities within the constrained minimal supersymmetric extension of the Standard Model (CMSSM), in which there are three independent soft supersymmetry-breaking parameters m_{1/2}, m_0 and A_0.

The Supersymmetric Parameter Space in Light of B-physics Observables and Electroweak Precision Data
/ Ellis, Jonathan Richard (CERN) ; Heinemeyer, S (Instituto de Fisica de Cantabria (CSIC-UC), Santander) ; Olive, K A (William I. Fine Theoretical Physics Institute, University of Minnesota, Minneapolis) ; Weber, A M (Max-Planck, Munich) ; Weiglein, G (IPPP, University of Durham)
Indirect information about the possible scale of supersymmetry (SUSY) breaking is provided by B-physics observables (BPO) as well as electroweak precision observables (EWPO). We combine the constraints imposed by recent measurements of the BPO BR(b -> s gamma), BR(B_s -> mu^+ mu^-), BR(B_u -> tau nu_tau) and Delta M_{B_s} with those obtained from the experimental measurements of the EWPO M_W, sin^2 theta_eff, Gamma_Z, (g-2)_mu and M_h, incorporating the latest theoretical calculations of these observables within the Standard Model and supersymmetric extensions.

On the Higgs Mass in the CMSSM
/ Ellis, John R. (CERN) ; Nanopoulos, Dimitri V. (Texas A-M ; HARC, Woodlands ; Athens Academy) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.) ; Santoso, Yudi (Victoria U. ; Perimeter Inst. Theor. Phys.)
We estimate the mass of the lightest neutral Higgs boson h in the minimal supersymmetric extension of the Standard Model with universal soft supersymmetry-breaking masses (CMSSM), subject to the available accelerator and astrophysical constraints. For m_t = 174.3 GeV, we find that 114 GeV < m_h < 127 GeV and a peak in the tan beta distribution simeq 55. [...]

Prediction for the Lightest Higgs Boson Mass in the CMSSM using Indirect Experimental Constraints
/ Buchmueller, O. ; Cavanaugh, R. ; De Roeck, A. ; Heinemeyer, S. ; Isidori, G. ; Paradisi, P. ; Ronga, F.J. ; Weber, A.M. ; Weiglein, G.
Measurements at low energies provide interesting indirect information about masses of particles that are (so far) too heavy to be produced directly. Motivated by recent progress in consistently and rigorously calculating electroweak precision observables and flavour related observables, we derive the *preferred* value for m_h in the Constrained Minimal Supersymmetric Standard Model (CMSSM), obtained from a fit taking into account electroweak precision data, flavour physics observables and the abundance of Cold Dark Matter.

Sensitivities to the SUSY Scale from Electroweak Precision Observables
/ Ellis, John R. (CERN) ; Heinemeyer, S. (CERN) ; Olive, K. (Minnesota U., Theor. Phys. Inst.) ; Weiglein, G. (Durham U., IPPP)
Precision measurements, now and at a future linear electron-positron collider (ILC), can provide indirect information about the possible scale of supersymmetry. Performing a chi^2 analysis, we illustrate the present-day and possible future ILC sensitivities within the constrained minimal supersymmetric extension of the Standard Model (CMSSM), varying the parameters so as to obtain the cold dark matter density allowed by WMAP and other cosmological data.

Electroweak Precision Observables in the Minimal Supersymmetric Standard Model
/ Heinemeyer, S (CERN) ; Hollik, W (MPI Munich, Germany) ; Weiglein, Georg (Univ. Durham, England)
The current status of electroweak precision observables in the Minimal Supersymmetric Standard Model (MSSM) is reviewed. We focus in particular on the $W$ boson mass, M_W, the effective leptonic weak mixing angle, sin^2 theta_eff, the anomalous magnetic moment of the muon, (g-2)_\mu, and the lightest CP-even MSSM Higgs boson mass, m_h.

Very Constrained Minimal Supersymmetric Standard Models
/ Ellis, John R. (CERN) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.) ; Santoso, Yudi (Minnesota U., Theor. Phys. Inst.) ; Spanos, Vassilis C. (Minnesota U., Theor. Phys. Inst.)
We consider very constrained versions of the minimal supersymmetric extension of the Standard Model (VCMSSMs) which, in addition to constraining the scalar masses m_0 and gaugino masses m_{1/2} to be universal at some input scale, impose relations between the trilinear and bilinear soft supersymmetry breaking parameters A_0 and B_0. These relations may be linear, as in simple minimal supergravity models, or nonlinear, as in the Giudice-Masiero mechanism for generating the Higgs-mixing mu term. [...]

The pMSSM10 after LHC Run 1
/ de Vries, K.J. (Imperial Coll., London) ; Bagnaschi, E.A. (DESY) ; Buchmueller, O. (Imperial Coll., London) ; Cavanaugh, R. (Fermilab ; Illinois U., Chicago) ; Citron, M. (Imperial Coll., London) ; De Roeck, A. (CERN ; Antwerp U.) ; Dolan, M.J. (SLAC ; Melbourne U.) ; Ellis, J.R. (King's Coll. London ; CERN) ; Flächer, H. (Bristol U.) ; Heinemeyer, S. (Cantabria Inst. of Phys.) et al.
We present a frequentist analysis of the parameter space of the pMSSM10, in which the following 10 soft SUSY-breaking parameters are specified independently at the mean scalar top mass scale Msusy = Sqrt[M_stop1 M_stop2]: the gaugino masses M_{1,2,3}, the 1st-and 2nd-generation squark masses M_squ1 = M_squ2, the third-generation squark mass M_squ3, a common slepton mass M_slep and a common trilinear mixing parameter A, the Higgs mixing parameter mu, the pseudoscalar Higgs mass M_A and tan beta. We use the MultiNest sampling algorithm with 1.2 x 10^9 points to sample the pMSSM10 parameter space. [...]
