Panglossian Prospects for Detecting Neutralino Dark Matter in Light of Natural Priors (2008)
Allanach, Benjamin C., Hooper, Dan
In most global fits of the constrained minimal supersymmetric model (CMSSM) to indirect data, the a priori likelihoods of any two points in tan beta are treated as equal, and the more fundamental mu...
Towards the European strategy for particle physics: the Briefing Book (2006)

This document was prepared as part of the briefing material for the Workshop of the CERN Council Strategy Group, held in DESY Zeuthen from 2nd to 6th May 2006. It gives an overview of the physics...
Supersymmetry Parameter Analysis : SPA Convention and Project (2005)
Aguilar-Saavedra, J A, Ali, A, Allanach, Benjamin C, Arnowitt, R, Baer, H A, Bagger, J A, ...
High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when...
Physics Interplay of the LHC and the ILC (2004)
Weiglein, Georg, Barklow, T, Boos, E, De Roeck, A, Desch, Klaus, Gianotti, F, ...
Physics at the Large Hadron Collider (LHC) and the International e+e- Linear Collider (ILC) will be complementary in many respects, as has been demonstrated at previous generations of hadron and...
Skands, P Z, Allanach, Benjamin C, Baer, Howard W, Balázs, C, Bélanger, G, Boudjema, F, ...
An accord specifying generic file structures for 1) supersymmetric model specifications and input parameters, 2) electroweak scale supersymmetric mass and coupling spectra, and 3) decay tables is...
The R-Parity Violating Minimal Supergravity Model (2003)
Allanach, Benjamin C, Dedes, A, Dreiner, H K
We present the minimal supersymmetric standard model with general broken R-parity, focusing on minimal supergravity (mSUGRA). We discuss the origins of lepton number violation in supersymmetry. We...
Theoretical uncertainties in sparticle mass predictions from computational tools (2003)
Allanach, Benjamin C, Kraml, Sabine, Porod, Werner
We estimate the current theoretical uncertainty in sparticle mass predictions by comparing several state-of-the-art computations within the minimal supersymmetric standard model (MSSM). We find that...
Allanach, Benjamin C, Sridhar, K
The CDF experiment reported a lepton photon missing transverse energy (E_T) signal 3 sigma in excess of the Standard Model prediction in Tevatron Run I data. The excess can be explained by the...
Allanach, Benjamin C, Lola, S, Sridhar, K
The recent excess over the Standard Model prediction in the \mu \gamma missing-E_T channel reported by CDF can be well-explained by resonant smuon production with a single dominant R-parity violating...
Selecting Supersymmetric String Scenarios From Sparticle Spectra (2001)
Allanach, Benjamin C, Grellscheid, D, Quevedo, Fernando
We approach the following question: if supersymmetry is discovered, how can we select among different supersymmetric extensions of the Standard Model? In particular, we perform an analysis of the...
Explaining Anomalous CDF $\mu$ $\gamma$ Missing-E$_{T}$ Events With Supersymmetry (2001)
Allanach, Benjamin C, Lola, S, Sridhar, K
CDF recently reported an excess of events in the mu-gamma-missing E_T channel that disagrees with the Standard Model prediction. No such excess was observed in the e-gamma-missing E_T channel. We...
SOFTSUSY: a C++ program for calculating supersymmetric spectra (2001)
SOFTSUSY is a C++ program which accurately calculates the spectrum of superparticles in the Minimal Supersymmetric Standard Model (MSSM). The program solves the renormalisation group equations with...
Physics at high $Q^{2}$ and $p^{2}_{t}$.: Summary of DIS 2000 (2000)
Kuze, M, Lola, S, Pérez, E, Allanach, Benjamin C
We summarize the experimental and theoretical results presented in the "Physics at the Highest Q^2 and p^2_t" working group at the DIS 2000 Workshop. High Q^2 and p^2_t processes measured at current...
Naturalness Reach of the Large Hadron Collider in Minimal Supergravity (2000)
Allanach, Benjamin C, Hetherington, J P J, Parker, M A, Webber, Bryan R
We re-analyse the prospects of discovering supersymmetry at the LHC, in order to re-express coverage in terms of a fine-tuning parameter and to extend the analysis to scalar masses (m_0) above 2 TeV....
Quasi-Fixed Points and Charge and Colour Breaking in Low Scale Models (1999)
Abel, S A, Allanach, Benjamin C
We show that the current LEP2 lower bound upon the MSSM lightest Higgs mass rules out quasi-fixed scenarios for string scales between 10^8 and 10^{14} GeV. We consider the implications for charge and...
Hybrid MSW + VO Solution of the Solar Neutrino Problem in String-Motivated Unified Theories (1997)
Allanach, Benjamin C, Leontaris, George K, Petcov, S T
It is shown that the hybrid MSW + VO solution of the solar neutrino problem, according to which the solar nu_e undergo matter-enhanced transitions into nu_mu, nu_tau in the Sun followed by long wave...

The Searches Working Group discussed a variety of topics relating to present and future measurements of searches at LEP 2. The individual contributions are included separately.
Yukawa Textures from Family Symmetry and Unification (1997)
Allanach, Benjamin C, King, S F, Leontaris, George K, Lola, S
In this letter, we show how the combination of both a gauged U(1)_X family symmetry and an extended vertical gauge symmetry in a single model, allows for the presence of additional Clebsch texture...
Allanach, Benjamin C, King, S F, Leontaris, George K, Lola, S
The origin of texture zeroes in the Yukawa matrices may be accounted for by appealing to a broken gauged family symmetry such as U(1)_X, where such symmetries arise naturally from string theories. In...
