Optimal minimal measurements of mixed states
G. Vidal, J. I. Latorre, P. Pascual +1
The optimal and minimal measuring strategy is obtained for a two-state system prepared in a mixed state with a probability given by any isotropic a priori distribution. We explicit…
A study of the centrally produced baryon-antibaryon systems in pp interactions at 450 GeV/c
The WA102 Collaboration, D. Barberis et al
A study of the centrally produced ppbar, ppbarpi, ppbarpipi and lambda lambda channels has been performed in pp collisions using an incident beam momentum of 450 GeV/c. No signific…
Measurement of the High-Mass Drell-Yan Cross Section and Limits on Quark-Electron Compositeness Scales
B. Abbott
We present a measurement of the Drell-Yan cross section at high dielectron invariant mass using 120/pb of data collected in pbar-p collisions at sqrt(s) = 1.8 TeV by the D0 collabo…
T-duality and Effective D-Brane Actions
Joan Simón
T-duality realized on D-brane effective actions is studied from a pure worldvolume point of view. It is proved that invariance in the form of the Dirac-Born-Infeld and Wess-Zumino…
Massive Fields of Arbitrary Integer Spin in Symmetrical Einstein Space
S. M. Klishevich
We study the propagation of gauge fields with arbitrary integer spins in the symmetrical Einstein space of any dimensionality. We reduce the problem of obtaining a gauge-invariant…
Matrix Elements of Electroweak Penguin Operators in the 1/Nc Expansion
M. Knecht, S. Peris, E. de Rafael
It is shown that the K -> pi pi matrix elements of the four-quark operator Q_7, generated by the electroweak penguin-like diagrams of the Standard Model, can be calculated to first…
Reduced phase space: quotienting procedure for gauge theories
J M Pons, D C Salisbury, L C Shepley
We present a reduction procedure for gauge theories based on quotienting out the kernel of the presymplectic form in configuration-velocity space. Local expressions for a basis of…
Polarization properties of diffractively produced Λ_c^+
Yu. Arestov, F. R. A. Simao
The Pomeron-gluon-gluon interaction is considered in the QCD-based model for the charmed baryon production in the process Pomeron + p --> Λ_c^+ + X. The polarization of the produce…
Probing a Nucleon Spin Structure at TESLA by the Real Polarized Gamma Beam
S. Alekhin, V. Borodulin, A. Celikel +2
The recent proposals concerning the usage of the real polarized gamma beam, obtained by the Compton backscattering of the laser photons off the electron beams from either the linea…
Search for the Standard Model Higgs boson at the LEP2 collider near sqrt(S) = 183GeV
ALEPH Collaboration
During 1997 the ALEPH experiment at LEP gathered 57pb^-1 of data at centre-of- mass energies near 183 GeV. These data are used to look for possible signals from the production of t…
Double Top Production at Hadronic Colliders
Yu. P. Gouz, S. R. Slabospitsky
We calculate the contribution of anomalous top-quark interaction with a gluon, photon, and -boson (FCNC) to pair production in hadronic collisions. Using the current…
Progress in classically solving ten dimensional supersymmetric reduced Yang-Mills theories
Jean-Loup Gervais, Mikhail Saveliev
It is shown that there exists an on-shell light cone gauge where half of the fermionic components of the super vector potential vanish, so that part of the superspace flatness cond…

D0 Collaboration, B. Abbott
A search has been carried out for events in the channel p-barp --> gamma gamma jet jet. Such a signature can characterize the production of a non-standard Higgs boson together with…
Spectrum of Cosmological Perturbations in the One-Bubble Open Universe
Jaume Garriga, Xavier Montes, Misao Sasaki +1
The spectrum of cosmological perturbations in the context of the one-bubble open inflation model is discussed, taking into account fluctuations of the metric. We find that, quite g…
