Ground State of the Quantum Symmetric Finite Size XXZ Spin Chain with Anisotropy Parameter
V. Fridkin, Yu. Stroganov, D. Zagier
We find an analytic solution of the Bethe Ansatz equations (BAE) for the special case of a finite XXZ spin chain with free boundary conditions and with a complex surface field whic…
The QCD renormalization scale stability of high twists and in deep inelastic scattering
Alekhin Sergey
A sensitivity of twist-4 and values extracted in the NLO QCD analysis of nonsinglet SLAC-BCDMS-NMC deep inelastic scattering data to the choice of QCD renormalization scale (…
Hard Single Diffraction in pbarp Collisions at root-s = 630 and 1800 GeV
The D0 Collaboration, B. Abbott
Using the D0 detector, we have studied events produced in proton-antiproton collisions that contain large forward regions with very little energy deposition (``rapidity gaps'') and…
The gauge group in the real triad formulation of general relativity
J. M. Pons, D. C. Salisbury, L. C. Shepley
We construct explicitly generators of projectable four-dimensional diffeomorphisms and triad rotation gauge symmetries in a model of vacuum gravity where the fundamental dynamical…
Gauge Transformations in Einstein-Yang-Mills Theories
J. M. Pons, D. C. Salisbury, L. C. Shepley
We discuss the relation between spacetime diffeomorphisms and gauge transformations in theories of the Yang-Mills type coupled with Einstein's General Relativity. We show that loca…
Gauge group and reality conditions in Ashtekar's complex formulation of canonical gravity
J. M. Pons, D. C. Salisbury, L. C. Shepley
We discuss reality conditions and the relation between spacetime diffeomorphisms and gauge transformations in Ashtekar's complex formulation of general relativity. We produce a gen…
The Isolated Photon Cross Section in p pbar Collisions at sqrt(s) = 1.8 TeV
D0 Collaboration, B. Abbott
We report a new measurement of the cross section for the production of isolated photons, with transverse energies (ET) above 10 GeV and pseudorapidities |eta| < 2.5, in p pbar coll…
Regge-Eikonal Approach and its off-Shell Extention Versus Experimental Data
V. A. Petrov, A. V. Prokudin
We develop an off-shell extention of the Regge-eikonal approach which automatically takes into account off-shell unitarity. We argue that exclusive vector-meson production cross-se…
Multiplicity distributions in e+e- annihilation into hadrons and pure birth branching processes
O. G. Tchikilev
Recursive solution for a general homogeneous in time pure birth branching process with simultaneous production of any number of particles and with continuous evolution parameter is…
A study of the etapipi channel produced in central pp interactions at 450 GeV/c
The WA102 Collaboration, D. Barberis
The reaction pp -> pf (eta pi pi) ps has been studied at 450 GeV/c. There is clear evidence for an a2(1320)pi decay mode of the eta2(1645) and eta2(1870). In addition, there is evi…
A spin analysis of the 4pi channels produced in central pp interactions at 450 GeV/c
The WA102 Collaboration, D. Barberis
The reactions pp -> pf (X0) ps, where X0 is observed decaying to pi0pi0pi0pi0, pi+pi-pi0pi0 and pi+pi-pi+pi-, have been studied at 450 GeV/c. There is evidence for an a2(1320)pi de…
Brane-world creation and black holes
Jaume Garriga, Misao Sasaki
An inflating brane-world can be created from ``nothing'' together with its Anti-de Sitter (AdS) bulk. The resulting space-time has compact spatial sections bounded by the brane. Du…
Production of light pseudoscalars in external electromagnetic fields by the Schwinger mechanism
J. A. Grifols, Eduard Masso, Subhendra Mohanty
We generalize the Schwinger mechanism and calculate the probability of the decay of intense electromagnetic fields to pseudoscalar particles. We also point out that our estimate fo…
Sensitivity of single crystals to the circular polarization of high-energy gamma-quanta
V. A. Maisheev
It is shown that single crystals are sensitive to the initial circular polarization of gamma-quanta with energies in tens GeV and more. The possibility of measurement of gamma-beam…

V. V. Ezhela, B. V. Polishchuk
We have made the comparison of three parametrizations of the proton electromagnetic form factors in the space-like region using the largest data set on elastic scatteri…

D0 Collaboration, B. Abbott
We report on a measurement of sigma(p-pbar to W+X) times B(W to tau+nu) in p-pbar collisions at sqrt(s) = 1.8 TeV at the Fermilab Tevatron. The measurement is based on an integrate…
