Vector supersymmetry of the superstring in the super-Beltrami parametrization
A. Boresch, M. Schweda, S. P. Sorella
The vector supersymmetry recently found for the bosonic string is generalized to superstring theories quantized in the super-Beltrami parametrization.
Lifetime, , and in the Heavy Quark Expansion
I. I. Bigi, N. G. Uraltsev
We present some straightforward applications of the QCD heavy quark expansion, stated in previous papers [1-3], to the inclusive widths of heavy flavour hadrons. We address the que…
Computing Masses and Surface Tension from Effective Transfer Matrices
M. Hasenbusch, K. Rummukainen, K. Pinn
We propose an effective transfer-matrix method that allows a measurement of tunnelling correlation lengths that are orders of magnitude larger than the lattice extension. Combining…
Aspects of the electroweak phase transition in the Minimal Supersymmetric Standard Model
A. Brignole, J. R. Espinosa, M. Quiros +1
We study the finite-temperature effective potential of the Minimal Supersymmetric Standard Model in the full (mA, tan(beta)) parameter space. As for the features of the electroweak…
What can we learn from a second phi meson peak in ultrarelativistic nuclear collisions?
Che Ming Ko, David Seibert
The decay width of a phi meson is reduced from its vacuum value as its mass decreases in hot hadronic matter as a result of the partial restoration of chiral symmetry. This reducti…
QCD Evolution Equations for High Energy Partons in Nuclear Matter
Klaus Geiger, Berndt Mueller
We derive a generalized form of Altarelli-Parisi equations to decribe the time evolution of parton distributions in a nuclear medium. In the framework of the leading logarithmic ap…
The Three--Point Correlation Function of the Cosmic Microwave Background in Inflationary Models
A. Gangui, F. Lucchin, S. Matarrese +1
We analyze the temperature three--point correlation function and the skewness of the Cosmic Microwave Background (CMB), providing general relations in terms of multipole coefficien…
Searching for an Invisibly Decaying Higgs Boson in E^+E^-, E-Gamma, and Gamma-Gamma Collisions
O. J. P. Eboli, M. C. Gonzalez-Garcia, A. Lopez-Fernandez +2
Higgs bosons can have a substantial ``invisible'' branching ratio in many extensions of the Standard Model, such as models where the Higgs bosons decay predominantly into light or…
One loop corrections to the Neutralino sector and Radiative Electroweak Breaking in the MSSM
A. B. Lahanas, K. Tamvakis, N. D. Tracas
We compute one loop radiative corrections to the physical neutralino masses in the MSSM considering the dominant top-stop contributions. We present a numerical renormalization grou…
Higher-Order Corrections to the Large- Bound on
S. Peris
Next-to-leading corrections to the upper bound on recently obtained by Georgi are considered. These corrections are just what is needed to reconcile the bound w…
The Finite Temperature Phase Transition in the Lattice SU(2)-Higgs Model
K. Farakos, K. Kajantie, K. Rummukainen +1
We study the finite temperature transition of SU(2)-Higgs model with lattice Monte Carlo techniques. We use dimensional reduction to transform the original 4-dimensional SU(2)-gaug…
Standard Model CP-violation and Baryon asymmetry
M. B. Gavela, P. Hernández, J. Orloff +1
Simply based on CP arguments, we argue against a Standard Model explanation of the baryon asymmetry of the universe in the presence of a first order phase transition. A CP-asymmetr…
Generalized Drinfeld-Sokolov Hierarchies, Quantum Rings, and W-Gravity
W. Lerche
We investigate the algebraic structure of integrable hierarchies that, we propose, underlie models of -gravity coupled to matter. More precisely, we concentrate on the dispersio…
The Relevance of the Dipole Penguin Operators in
S. Bertolini, M. Fabbrichesi, E. Gabrielli
The standard model contribution to of the magnetic- and electric-dipole penguin operators …
The Electric Charge of Neutrinos and Plasmon Decay
T. Altherr, P. Salati
By using both thermal field theory and a somewhat more intuitive method, we define the electric charge as well as the charge radius of neutrinos propagating inside a plasma. We sho…
Can EROS/MACHO be detecting the galactic spheroid instead of the galactic halo?
G. F. Giudice, S. Mollerach, E. Roulet
Models of our galaxy based on dynamical observations predict a spheroid component much heavier than accounted for by direct measurements of star counts and high velocity stars. If,…
Strong Sphalerons and Electroweak Baryogenesis
G. Giudice, M. Shaposhnikov
We analyze the spontaneous baryogenesis and charge transport mechanisms suggested by Cohen, Kaplan and Nelson for baryon asymmetry generation in extended versions of electroweak th…
Thermal quark production in ultra-relativistic nuclear collisions
Tanguy Altherr, David Seibert
We calculate thermal production of u, d, s, c and b quarks in ultra-relativistic heavy ion collisions. The following processes are taken into account: thermal gluon decay (g to iba…
Running Coupling in SU(3) Yang-Mills Theory
Ulli Wolff
We report about our ongoing computation of running coupling constants in asymptotically free theories using the recursive finite size scaling technique. The latest results for the…
Anathematizing the Guralnik and Manohar Inequality for \barΛ
I. I. Bigi, N. G. Uraltsev
There is a recent claim by Guralnik and Manohar \cite{GM} to have established a rigorous lower bound on , the asymptotic difference between the mass of a heavy flavour {\em…
Subleading Corrections to Semileptonic Lambda_c Decays
Guey-Lin Lin, Thomas Mannel
The semileptonic decay is considered in the framework of heavy quark effective theory beyond the leading order in the expansion. According to our estimate…
QCD-Based Interpretation of the Lepton Spectrum in Inclusive Decays
Matthias Neubert
We present a QCD-based approach to the endpoint region of the lepton spectrum in decays. We introduce a genuinely nonperturbative form factor, the shap…
On a `universal' class of WZW-type conformal models
A. A. Tseytlin
We consider a class of sigma models that appears from a generalisation of the gauged WZW model parametrised by a constant matrix . Particular values of correspond to the sta…
New Black Hole, String and Membrane Solutions of the Four-Dimensional Heterotic String
M. J. Duff, Ramzi R. Khuri, Ruben Minasian +1
We present solutions of the low-energy four-dimensional heterotic string corresponding to -branes with , which are characterized by a mass per unit -volume, ${\cal M…
