Constraints on the Minimal SUSY SO(10) Model from Cosmology and the Decay
F. M. Borzumati, M. Olechowski, S. Pokorski
It is shown that the minimal supersymmetric SO(10) model with electroweak radiative breaking and universal soft mass terms at the GUT scale is strongly disfavoured by the combinati…
Two-loop electroweak top corrections: are they under control?
G. Degrassi, S. Fanchiotti, F. Feruglio +2
The assumption that two-loop top corrections are well approximated by the contribution is investigated. It is shown that in the case of the ratio neutral-to-charge…
Topological Strings from WZW Models
K. Landsteiner, W. Lerche, A. Sevrin
We show that the BRST structure of the topological string is encoded in the ``small'' superconformal algebra, enabling us to obtain, in a non-trivial way, the string theory f…
The Refined Elliptic Genus and Coulomb Gas Formulations of Superconformal Coset Models
D. Nemeschansky, N. P. Warner
We describe, in some detail, a number of different Coulomb gas formulations of superconformal coset models. We also give the mappings between these formulations. The ultimate…
Total Cross Sections for Heavy Flavour Production at HERA
S. Frixione, M. L. Mangano, P. Nason +1
We compute total cross sections for charm and bottom photoproduction at HERA energies, and discuss the relevant theoretical uncertainties. In particular we discuss the problems ari…
Supersymmetry dileptons and trileptons at the Tevatron
J. Lopez, D. Nanopoulos, X. Wang +1
We consider the production of supersymmetry neutralinos and charginos in collisions at the Tevatron, and their subsequent decay via hadronically quiet dileptons and trile…
On the large- behavior of the coupling in PT
Santiago Peris, Eduardo de Rafael
It is shown that the usual large- counting of the coupling constant of the low-energy chiral Lagrangian \cite{GL85} is in conflict with general…
HQQET: An Effective Theory Approach to Heavy Quarkonia Decays
Thomas Mannel, Gerhard Schuler
We discuss systems containing a heavy quark and a heavy antiquark in the infinite mass limit of QCD. Studying the limit of equal velocities for both heavy particles, we formulate a…
Abundant phi-Meson Production in pbar-p Annihilation at Rest and Strangeness in the Nucleon
J. Ellis, M. Karliner, D. E. Kharzeev +1
A large apparent violation of the OZI rule has recently been found in many channels in pbar-p annihilation LEAR. An interpretation of these data in terms of the "shake-out" and "re…
Results from a Non-Perturbative Renormalization of Lattice Operators
G. Martinelli, C. Pittori, C. T. Sachrajda +2
We propose a general renormalization method, which avoids completely the use of lattice perturbation theory. We present the results from its numerical applications to two-fermion o…
3d physics and the electroweak phase transition: a framework for lattice Monte Carlo analysis
K. Farakos, K. Kajantie, K. Rummukainen +1
We discuss a framework relying on both perturbative and non-perturbative lattice computations which will be able to reliably determine the parameters of the EW phase transition. A…
Spatial Geometry and the Wu-Yang Ambiguity
Daniel Z. Freedman, Ramzi R. Khuri
We display continuous families of SU(2) vector potentials in 3 space dimensions which generate the same magnetic field (with det ). These Wu-Yang fa…
Heavy-light baryonic mass splittings from the lattice
C. Alexandrou, A. Borrelli, S. Guesken +4
We present lattice estimates of the mass of the heavy-light baryons and obtained using propagating heavy quarks. For our result is $M_{Λ_b}=5.728 \pm 0.144 \pm 0.…
The renormalization group inspired approaches and estimates of the tenth-order corrections to the muon anomaly in QED
Andrei L. Kataev, Valery V. Starshenko
We present the estimates of the five-loop QED corrections to the muon anomaly using the scheme-invariant approaches and demonstrate that they are in good agreement with the results…
Supersymmetric Unification
Savas Dimopoulos
The measured value of the weak mixing angle is, at present, the only precise experimental indication for physics beyond the Standard Model. It points in the direction of Unified Th…
Scale Setting in QCD and the Momentum Flow in Feynman Diagrams
Matthias Neubert
We present a formalism to evaluate QCD diagrams with a single virtual gluon using a running coupling constant at the vertices. This method, which corresponds to an all-order resumm…
Mirror Symmetry for Calabi-Yau Hypersurfaces in Weighted P_4 and Extensions of Landau Ginzburg Theory
Philip Candelas, Xenia de la Ossa, Sheldon Katz
Recently two groups have listed all sets of weights (k_1,...,k_5) such that the weighted projective space P_4^{(k_1,...,k_5)} admits a transverse Calabi-Yau hypersurface. It was no…
Discrete Gravity in One Dimension
Herbert W. Hamber, Ruth M. Williams
A model for quantum gravity in one (time) dimension is discussed, based on Regge's discrete formulation of gravity. The nature of exact continuous lattice diffeomorphisms and the i…
Renormalons on the Lattice
M. Crisafulli, V. Gimenez, G. Martinelli +1
We present the first lattice calculation of the B-meson binding energy $\labar$ and of the kinetic energy of the heavy-quark inside the pseudoscalar B-meson. In order t…
--Parity Violating SUSY or Leptoquarks: Virtual Effects in Dilepton Production
Gautam Bhattacharyya, Debajyoti Choudhury, K. Sridhar
In the Standard Model (SM), dilepton production in hadron--hadron collisions proceeds through the conventional Drell--Yan mechanism with the exchang…
Production of Heavy Selectrons in Electron-Photon Collisions
Debajyoti Choudhury, Frank Cuypers
We study the production and decay of heavy selectrons in the electron-photon mode of a linear collider of the next generation. The standard model backgrounds can be substantially r…
Direct detection of dark matter in SU(5)xU(1) supergravity
X. Wang, J. Lopez, D. Nanopoulos
We compute the scattering rates for the lightest neutralino in the forthcoming germanium detector and a proposed lead detector $(^{207}{\rm…
On the Space-Time Geometry of Quantum Systems
Dirk Graudenz
We describe the time evolution of quantum systems in a classical background space-time by means of a covariant derivative in an infinite dimensional vector bundle. The correspondin…
String no-scale supergravity
J. Lopez, D. Nanopoulos
We explore the postulates of string no-scale supergravity in the context of free-fermionic string models. The requirements of vanishing vacuum energy, flat directions of the scalar…
