Two-dimensional Yang-Mills theory: perturbative and instanton contributions, and its relation to QCD in higher dimensions
A. Bassetto
Two different scenarios (light-front and equal-time) are possible for Yang-Mills theories in two dimensions. The exact -potential can be derived in perturbation theory st…
The OSp(1|4) Superparticle and Exotic BPS States
Igor Bandos, Jerzy Lukierski, Dmitri Sorokin
We discuss the dynamics of a superparticle in a superspace whose isometry is generated by the superalgebra OSp(1|4) or its central-charge contraction. Extra coordinates of the supe…
Jet dynamics in black hole physics: acceleration during subparsec collimation
F. de Felice, O. Zanotti
We study the processes of particle acceleration which take place in the field of a rotating black hole as part of a mechanism of formation of galactic jets within the first parsec…
Isoscalar off-shell effects in threshold pion production from pd collisions
L. Canton, W. Schadow
We test the presence of pion-nucleon isoscalar off-shell effects in the reaction around the threshold region. We find that these effects significantly modify the prod…
On the form of Lorentz-Stern-Gerlach force
Sameen Ahmed Khan, Modesto Pusterla
In recent times there has been a renewed interest in the force experienced by a charged-particle with anomalous magnetic moment in the presence of external fields. In this paper we…
Search for Scalar Top and Scalar Bottom Quarks in collisions at TeV
CDF Collaboration
We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb of collisions at TeV with the CDF detector. We looked f…
Production of Y(1S) Mesons from chib Decays in pp(bar) Collisions at sqrt(s)=1.8 TeV
CDF Collaboration, T. Affolder
We have reconstructed the radiative decays and in collisions at TeV, and measured the fraction of $Υ(1S…
Gauge field theory of transport and magnetic relaxation in underdoped cuprates
P. A. Marchetti, Jian-Hui Dai, Zhao-Bin Su +1
Based on recently proposed U(1)xSU(2) Chern-Simons gauge field theory, an interpretation of the transport and magnetic relaxation properties of underdoped cuprates is proposed, tak…
Macroscopic Forces driven by Resonant Neutrino Conversion
Dario Grasso, Anna Rossi
We show that neutrino oscillations in matter are always accompanied by collective forces on the medium. This effect may produce interesting consequences for the background and the…
Search for Charmless Hadronic Decays of B Mesons with the SLD Detector
SLD Collaboration
Based on a sample of approximately 500,000 hadronic Z0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body e…
Search for a W' Boson via the Decay Mode W' -> mu nu in 1.8 TeV p-pbar Collisions
CDF Collaboration, F. Abe
We report the results of a search for a W' boson produced in p-pbar collisions at a center-of-mass energy of 1.8 TeV using a 107 pb-1 data sample recorded by the Collider Detector…
Gravitational Waves Signals from the Collapse of the First Stars
R. Schneider, A. Ferrara, B. Ciardi +2
We study the gravitational wave emission from the first stars which are assumed to be Very Massive Objects (VMOs). We take into account various feedback (both radiative and stellar…
Measurement of the Helicity of W Bosons in Top Quark Decays
CDF Collaboration, T. Affolder
We use the transverse momentum spectrum of leptons in the decay chain t-->bW with W-->l nu to measure the helicity of the W bosons in the top quark rest frame. Our measurement uses…
Search for a Fourth-Generation Quark More Massive than the Z0 Boson in ppbar Collisions at sqrt(s) = 1.8 TeV
CDF Collaboration, T. Affolder
We present the results of a search for pair production of a fourth-generation charge -1/3 quark (b') in sqrt(s)=1.8 TeV ppbar collisions using 88 pb^(-1) of data obtained with the…
Measurement of b Quark Fragmentation Fractions in p-pbar Collisions at sqrt(s)=1.8 TeV
T. Affolder, CDF Collaboration
We have studied the production of B hadrons in 1.8-TeV p-pbar collisions. We present measurements of the fragmentation fractions, f_u, f_d, f_s and f_baryon, of produced b quarks t…
Equivalence Principle, Higher Dimensional Moebius Group and the Hidden Antisymmetric Tensor of Quantum Mechanics
Gaetano Bertoldi, Alon E. Faraggi, Marco Matone
We show that the recently formulated Equivalence Principle (EP) implies a basic cocycle condition both in Euclidean and Minkowski spaces, which holds in any dimension. This conditi…
Role of break-up processes in fusion enhancement of drip-line nuclei at energies below the Coulomb barrier
K. Hagino, A. Vitturi, C. H. Dasso +1
We carry out realistic coupled-channels calculations for Be + Pb reaction in order to discuss the effects of break-up of the projectile nucleus on sub-barrier fusion…
Measurement of the B0 anti-B0 oscillation frequency using l- D*+ pairs and lepton flavor tags
CDF Collaboration, T. Affolder
The oscillation frequency Delta-md of B0 anti-B0 mixing is measured using the partially reconstructed semileptonic decay anti-B0 -> l- nubar D*+ X. The data sample was collected wi…
Triple Pomeron and Proton Diffraction Dissociation
R. Fiore, A. Flachi, L. L. Jenkovszky +2
We consider proton diffraction dissociation in the dipole Pomeron model, where the Pomeron is represented by a double pole in the plane, and show that unitarity can be satisfie…
Towards a grand unified picture for neutrino and quark mixings
Zurab Berezhiani, Anna Rossi
The comparison of the CKM mixing angles with the leptonic mixings implied by the recent atmospheric and solar neutrino data exhibits an interesting complementarity. This pattern ca…
The hypothesis of a real Cabibbo Kobayashi Maskawa matrix
P. Checchia, E. Piotto, F. Simonetto
The hypothesis of a real Cabibbo-Kobayashi-Maskawa matrix has been considered and found to be disfavoured by present measurements even when neglecting results from CP violation in…
Band termination in the N=Z Odd-Odd Nucleus 46V
S. M. Lenzi, D. R. Napoli, C. A. Ur +16
High spin states in the odd-odd N=Z nucleus 46V have been identified. At low spin, the T=1 isobaric analogue states of 46Ti are established up to I = 6+. Other high spin states, in…
