A More Minimal Messenger Model of Gauge-Mediated Supersymmetry Breaking?

G. Dvali, M. Shifman

This Letter addresses a provocative question: ``Can the standard electroweak Higgs doublets and their color-triplet partners be the messengers of a low energy gauge-mediated SUSY b…

Solvable Lie Algebras in Type IIA, Type IIB and M Theories

L. Andrianopoli, R. D'Auria, S. Ferrara +3

We study some applications of solvable Lie algebras in type IIA, type IIB and M theories. RR and NS generators find a natural geometric interpretation in this framework. Special em…

Type IIB instanton as a wave in twelve dimensions

A. A. Tseytlin

0-brane of type IIA string theory can be interpreted as a dimensional reduction of a gravitational wave in 11 dimensions. We observe that a similar interpretation applies also to t…

Four-jet Signal at LEP2 and Supersymmetry

M. Carena, G. F. Giudice, S. Lola +1

ALEPH has reported a significant excess of four-jet events in the LEP runs above the Z^0 resonance, which however has not been confirmed by the other LEP collaborations. We assume…

Supersymmetry, Supergravity and R_b revisited in the light of LEP 2

J. Ellis, J. Lopez, D. Nanopoulos

A previous study of supersymmetric models has indicated that they are unlikely to make a large contribution to R_b. We revisit this analysis, taking into account the improved lower…

Nuclear Attenuation of Fast Hadrons Produced in Charged-Current Neutrino and Antineutrino Interactions in Neon

WA59 Collaboration, W. Burkot, T. Coghen +11

The production of hadrons in charged-current (anti)neutrino interactions is studied with the bubble chamber BEBC exposed ot the CERN (anti)neutrino wide-band beam. Fast-hadron prod…

Theoretical Aspects of the Heavy Quark Expansion

N. Uraltsev

I give a brief outline of the theoretical framework for the modern treatment of the strong interaction effects in heavy quark decays, based on first principles of QCD. This model-i…

Non-Perturbative Corrections to Heavy Quark Fragmentation in e^+e^- Annihilation

P. Nason, B. R. Webber

We estimate the non-perturbative power-suppressed corrections to heavy flavour fragmentation and correlation functions in e^+e^- annihilation, using a model based on the analysis o…

Tilted Hybrid Inflation

Juan Garcia-Bellido, Andrei Linde

We propose a new version of the hybrid inflation scenario that produces a significantly tilted n>1 spectrum of curvature perturbations. This may happen in supersymmetric models whe…

F^4 Terms in N=4 String Vacua

C. Bachas, E. Kiritsis

We discuss $F_{μν}^{4}$ terms in torroidal compactifications of type-I and heterotic SO(32) string theory. We give a simple argument why only short BPS multiplets contribute to these…

Confining String with Topological Term

M. C. Diamantini, F. Quevedo, C. A. Trugenberger

We consider several aspects of `confining strings', recently proposed to describe the confining phase of gauge field theories. We perform the exact duality transformation that lead…

Gauge Invariance of Resummation Schemes: The QCD Partition Function

Marc Achhammer, Ulrich Heinz, Stefan Leupold +1

We pick up a method originally developed by Cheng and Tsai for vacuum perturbation theory which allows to test the consistency of different sets of Feynman rules on a purely diagra…

Renormalization of Velocity-Changing Dimension-Five Operators in the Heavy-Quark Effective Theory

G. Amorós, M. Neubert

We study the renormalization of operators of the type $h ˉ_{v^{'}} Γ G^{μν} h_{v}$ in the heavy-quark effective theory (HQET). We construct the combinations of such operators that a…

A Non-Perturbative Analysis of the Finite T Phase Transition in SU(2)xU(1) Electroweak Theory

K. Kajantie, M. Laine, K. Rummukainen +1

The continuum 3d SU(2) $\times$ U(1)+Higgs theory is an effective theory for a large class of 4d high-temperature gauge theories, including the minimal standard model and some of its…

Bottom-up approach and supersymmetry breaking

M. Carena, P. H. Chankowski, M. Olechowski +2

We present a bottom-up approach to the question of supersymmetry breaking in the MSSM. Starting with the experimentally measurable low-energy supersymmetry breaking parameters, whi…

Jet cross sections at next-to-leading order

Stefano Catani, Michael H. Seymour

We briefly summarize theoretical methods for carrying out QCD calculations to next-to-leading order in perturbation theory. In particular, we describe a new general algorithm that…

Classical Duality from dimensional reduction of Self Dual 4-form Maxwell Theory in 10 dimensions

D. S. Berman

By dimensional reduction of a self dual p-form theory on some compact space, we determine the duality generators of the gauge theory in 4 dimensions. In this picture duality is see…

Domain Walls in Strongly Coupled Theories

G. Dvali, M. Shifman

Domain walls in strongly coupled gauge theories are discussed. A general mechanism is suggested automatically leading to massless gauge bosons localized on the wall. In one of the…

U-Duality and Central Charges in Various Dimensions Revisited

L. Andrianopoli, R. D'Auria, S. Ferrara

A geometric formulation which describes extended supergravities in any dimension in presence of electric and magnetic sources is presented. In this framework the underlying duality…

A Prediction for the 4-Loop βFunction

John Ellis, Marek Karliner, Mark. A. Samuel

We predict that the four-loop contribution β_3 to the QCD βfunction in the MS-bar prescription is given by β_3\simeq 23,600(900) - 6,400(200) N_f + 350(70) N_f^2 + 1.5 N_f^3, where…
