A Twin Higgs Model from Left-Right Symmetry

Z. Chacko, Hock-Seng Goh, Roni Harnik

We present twin Higgs models based on the extension of the Standard Model to left-right symmetry that protect the weak scale against radiative corrections up to scales of order 5 T…

Supersymmetry Parameter Analysis: SPA Convention and Project

J. A. Aguilar-Saavedra, A. Ali, B. C. Allanach +122

High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is…

Theory of Neutrinos: A White Paper

R. N. Mohapatra, S. Antusch, K. S. Babu +29

During 2004, four divisions of the American Physical Society commissioned a study of neutrino physics to take stock of where the field is at the moment and where it is going in the…

Renormalization Scale-Fixing for Complex Scattering Amplitudes

Stanley J. Brodsky, Felipe J. Llanes-Estrada

We show how to fix the renormalization scale for hard-scattering exclusive processes such as deeply virtual meson electroproduction by applying the BLM prescription to the imaginar…

Determination of MSSM Parameters from LHC and ILC Observables in a Global Fit

Philip Bechtle, Klaus Desch, Werner Porod +1

We present the results of a realistic global fit of the Lagrangian parameters of the Minimal Supersymmetric Standard Model assuming universality for the first and second generation…

Simplified Unitarity Triangles for the Lepton Sector

James D. Bjorken, P. F. Harrison, W. G. Scott

Encouraged by the latest SNO results, we consider the lepton mixing matrix in the approximation that the nu_2 mass eigenstate is trimaximally (democratically) mixed. This suggests…

Baryon Number Violation Involving Higher Generations

Wei-Shu Hou, Makiko Nagashima, Andrea Soddu

Proton stability seems to constrain rather strongly any baryon number violating process. We investigate the possibility of baryon number violating processes involving right-handed…

Scaling properties of high p_T inclusive hadron production

S. J. Brodsky, H. J. Pirner, J. Raufeisen

We analyze the scaling properties of inclusive hadron production in proton-proton and in heavy ion collisions from fixed target to collider energies. At large transverse momentum p…

Applications of AdS/CFT Duality to QCD

Stanley J. Brodsky, Guy F. de Teramond

Even though quantum chromodynamics is a broken conformal theory, the AdS/CFT correspondence has led to important insights into the properties of QCD. For example, as shown by Polch…

Dark Matter before the LHC in a Natural Supersymmetric Standard Model

Ryuichiro Kitano, Yasunori Nomura

We show that the solid lower bound of about 10^{-44} cm^2 is obtained for the cross section between the supersymmetric dark matter and nucleon in a theory in which the supersymmetr…

The B --> pi form factor from light-cone sum rules in soft-collinear effective theory

Fulvia De Fazio, Thorsten Feldmann, Tobias Hurth

Recently, we have derived light-cone sum rules for exclusive B-meson decays into light energetic hadrons from correlation functions within soft-collinear effective theory. In these…

A precise sum rule among four B -> Kpi CP asymmetries

Michael Gronau

A sum rule relation is proposed for direct CP asymmetries in decays. Leading terms are identical in the isospin symmetry limit, while subleading terms are equal in the fl…

A Solution to the Supersymmetric Fine-Tuning Problem within the MSSM

Ryuichiro Kitano, Yasunori Nomura

Weak scale supersymmetry has a generic problem of fine-tuning in reproducing the correct scale for electroweak symmetry breaking. The problem is particularly severe in the minimal…

Comment on form factor shape and extraction of |V_ub| from B --> pi l nu

Thomas Becher, Richard J. Hill

We point out that current experimental data for partial B --> pi l nu branching fractions reduce the theoretical input required for a precise extraction of |V_ub| to the form facto…

Two-boson truncation of Pauli-Villars-regulated Yukawa theory

S. J. Brodsky, J. R. Hiller, G. McCartor

We apply light-front quantization, Pauli-Villars regularization, and numerical techniques to the nonperturbative solution of the dressed-fermion problem in Yukawa theory in 3+1 dim…

Enhanced KL to pi0 nu nubar from Direct CP Violation in B to K pi with Four Generations

Wei-Shu Hou, Makiko Nagashima, Andrea Soddu

Recent CP violation results in B decays suggest that Z penguins may have large weak phase. This can be realized by the four generation (standard) model. Concurrently, B to Xs l+ l-…

Stopping Gluinos

A. Arvanitaki, S. Dimopoulos, A. Pierce +2

Long lived gluinos are the trademark of split supersymmetry. They form R-hadrons that, when charged, efficiently lose energy in matter via ionisation. Independent of R-spectroscopy…

Off-the-Wall Higgs in the Universal Randall-Sundrum Model

Hooman Davoudiasl, Ben Lillie, Thomas G. Rizzo

We outline a consistent Randall-Sundrum (RS) framework in which a fundamental 5-dimensional Higgs doublet induces electroweak symmetry breaking (EWSB). In this framework of a warpe…

Lorentz Violation in Extra Dimensions

Thomas G. Rizzo

In theories with extra dimensions it is well known that the Lorentz invariance of the -dimensional spacetime is lost due to the compactified nature of the dimensions lea…

Recent Developments in Perturbative QCD

Lance J. Dixon

I review recent progress in perturbative QCD on two fronts: extending next-to-next-to-leading order QCD corrections to a broader range of collider processes, and applying twistor-s…

Nearly Conformal QCD and AdS/CFT

Guy F. de Teramond, Stanley J. Brodsky

The AdS/CFT correspondence is a powerful tool to study the properties of conformal QCD at strong coupling in terms of a higher dimensional dual gravity theory. The power-law fallof…

Determination of Littlest Higgs model parameters at the ILC

John A. Conley, JoAnne Hewett, My Phuong Le

We examine the effects of the extended gauge sector of the Littlest Higgs model in high energy e+e- collisions. We find that the search reach in e+e- -> f fbar at a 500 GeV center-…

Bootstrapping Multi-Parton Loop Amplitudes in QCD
