Covariant actions for chiral supersymmetric bosons
Kurt Lechner
We review a recently developed covariant Lagrangian formulation for --forms with (anti)self-dual field-strengths and present its extension to the supersymmetric case. As explici…
A class of two-dimensional Yang-Mills vacua and their relation to the non-linear sigma model
A. Bassetto, G. Nardelli
Classical vacuum - pure gauge - solutions of Euclidean two-dimensional SU(2) Yang-Mills theories are studied. Topologically non-trivial vacua are found in a class of gauge group el…
Observation of Hadronic W Decays in t-tbar Events with the Collider Detector at Fermilab
F. Abe
We observe hadronic W decays in t-tbar -> W (-> l nu) + >= 4 jet events using a 109 pb-1 data sample of p-pbar collisions at sqrt{s} = 1.8 TeV collected with the Collider Detector…
The Role of dimensionality in the stability of a confined Bose gas
Luca Salasnich
We study analytically the ground-state stability of a Bose-Einstein condensate (BEC) confined in an harmonic trap with repulsive or attractive zero-range interaction by minimizing…
Excited States in 52Fe and the Origin of the Yrast Trap at I=12+
C. A. Ur, D. Bucurescu, S. M. Lenzi +15
Excited states in 52Fe have been determined up to spin 10\hbar in the reaction 28Si + 28Si at 115 MeV by using γ-ray spectroscopy methods at the GASP array. The excitation energy o…
N=2 SYM RG Scale as Modulus for WDVV Equations
G. Bertoldi, M. Matone
We derive a new set of WDVV equations for N=2 SYM in which the renormalization scale is identified with the distinguished modulus which naturally arises in topological field th…
Infrared singularities in the null-plane bound-state equation when going to 1+1 dimensions
A. Bassetto
In this paper we first consider the null-plane bound-state equation for a pair in 1+3 dimensions and in the lowest-order Tamm-Dancoff approximation. Light-cone gauge is…
Measurement of the B0 B0-bar oscillation frequency using pi-B meson charge-flavor correlations in p p-bar collisions at sqrt{s} = 1.8 TeV
CDF Collaboration, F. Abe et. al
We present a measurement of the B0 B0-bar oscillation frequency using a flavor tagging method based on correlations of B meson flavor with the charge of other particles produced in…
Macroscopic String-like Solutions in Massive Supergravity
Harvendra Singh
In this report we obtain explicit string-like solutions of equations of motion of massive heterotic supergravity recently obtained by Bergshoeff, Roo and Eyras. We also find consis…
The Equivalence Principle of Quantum Mechanics: Uniqueness Theorem
Alon E. Faraggi, Marco Matone
Recently we showed that the postulated diffeomorphic equivalence of states implies quantum mechanics. This approach takes the canonical variables to be dependent by the relation p=…
Signals of a superlight gravitino at e^+ e^- colliders when the other superparticles are heavy
Andrea Brignole, Ferruccio Feruglio, Fabio Zwirner
If the gravitino G is very light and all the other supersymmetric particles are above threshold, supersymmetry may still be found at colliders, by looking at processes with only gr…
Weak Electric Dipole Moments of Heavy Fermions in the MSSM
W. Hollik, J. I. Illana, S. Rigolin +1
A minimal supersymmetric version of the Standard Model with complex parameters allows contributions to the weak-electric dipole moments of fermions at the one-loop level. Assuming…
Covariant actions for N=1, D=6 Supergravity theories with chiral bosons
G. Dall'Agata, K. Lechner, M. Tonin
We show that the recently found covariant formulation for chiral --forms in dimensions with even, can be naturally extended to supersymmetric theories. We present t…

P. A. Marchetti, Zhao-bin Su, Lu Yu
The Chern-Simons gauge theory is applied to study the 2-D model describing the normal state of underdoped cuprate superconductors. The U(1) field produces…
Neutrino masses and flavor symmetries
G. Costa, E. Lunghi
The problem of neutrino masses and mixing angles is analysed in a class of supersymmetric grand unified models, with SO(10) gauge symmetry and global U(2) flavour symmetry. Adoptin…
Quantum Zeno Effect with the Feynman-Mensky Path-Integral Approach
Roberto Onofrio, Carlo Presilla, Ubaldo Tambini
A model for quantum Zeno effect based upon an effective Schrödinger equation originated by the path-integral approach is developed and applied to a two-level system simultaneously…
On the effective interactions of a light gravitino with matter fermions
Andrea Brignole, Ferruccio Feruglio, Fabio Zwirner
If the gravitino is light and all the other supersymmetric particles are heavy, we can consider the effective theory describing the interactions of its goldstino components with or…
Coalescing binary systems of compact objects: Dynamics of angular momenta
Carlo Del Noce, Giovanni Preti, Fernando de Felice
The end state of a coalescing binary of compact objects depends strongly on the final total mass M and angular momentum J. Since gravitational radiation emission causes a slow evol…
