Bose-Einstein correlations in one and two dimensions in deep inelastic scattering
ZEUS Collaboration
Bose-Einstein correlations in one and two dimensions have been studied in deep inelastic EP scattering events measured with the ZEUS detector at HERA using an integrated luminosity…
Isolated tau leptons in events with large missing transverse momentum at HERA
ZEUS collaboration
A search for events containing isolated tau leptons and large missing transverse momentum, not originating from the tau decay, has been performed with the ZEUS detector at the elec…
Pseudoknots in a Homopolymer
A. Kabakcioglu, A. L. Stella
After a discussion of the definition and number of pseudoknots, we reconsider the self-attracting homopolymer paying particular attention to the scaling of the number of pseudoknot…
New analytic solutions of the collective Bohr hamiltonian for a beta-soft, gamma-soft axial rotor
Lorenzo Fortunato, Andrea Vitturi
New analytic solutions of the quadrupole collective Bohr hamiltonian are proposed, exploiting an approximate separation of the beta and gamma variables to describe gamma-soft prola…
Top Quark Measurements at the Fermilab Tevatron
P. Azzi
The top quark, discovered at the Tevatron in 1995, is a very interesting particle. Precise measurement of the top properties using large data samples will allow stringent tests of…
Loop Equation in Two-dimensional Noncommutative Yang-Mills Theory
Harald Dorn, Alessandro Torrielli
The classical analysis of Kazakov and Kostov of the Makeenko-Migdal loop equation in two-dimensional gauge theory leads to usual partial differential equations with respect to the…
Observation of the Narrow State in Collisions at $\sqrt{s}=1.96 \TeV$
the CDF II Collaboration, D. Acosta, T. Affolder +8
We report the observation of a narrow state decaying into and produced in of collisions at in the CDF II experiment. We o…
Search for pairing-vibration states of even Ca isotopes in Ca+Pb transfer reactions
S. Szilner, L. Corradi, B. R. Behera +14
Multi-nucleon transfer reactions in Ca+Pb have been studied at several bombarding energies close to the Coulomb barrier. Light reaction products have been identified…
Massive Gravity on a Brane
Z. Chacko, M. Graesser, C. Grojean +1
At present no theory of a massive graviton is known that is consistent with experiments at both long and short distances. The problem is that consistency with long distance experim…
Precise toppling balance, quenched disorder, and universality for sandpiles
R. Karmakar, S. S. Manna, A. L. Stella
A single sandpile model with quenched random toppling matrices captures the crucial features of different models of self-organized criticality. With symmetric matrices avalanche st…
Non-linear perturbations in scalar-tensor cosmologies
F. Perrotta, S. Matarrese, M. Pietroni +1
Can local fluctuations of a ``Quintessence'' scalar field play a dynamical role in the gravitational clustering and cosmic structure formation process? We address this question in…
One-loop unitarity of string theories in a constant external background and their Seiberg-Witten limit
A. Bassetto, A. Torrielli, R. Valandro
Perturbative spectra and related factorization properties of one-loop open string amplitudes in the presence of a constant external background B are analysed in detail. While the p…
Measurement of the polar-angle distribution of leptons from W boson decay as a function of the W transverse momentum in proton-antiproton collisions at sqrt{s}=1.8 TeV
L. Cerrito
We present a measurement of the coefficient alpha_2 of the leptonic polar-angle distribution from W boson decays, as a function of the W transverse momentum. The measurement uses a…
Two-Loop Vertices in Quantum Field Theory: Infrared Convergent Scalar Configurations
A. Ferroglia, G. Passarino, M. Passera +1
A comprehensive study is performed of general massive, scalar, two-loop Feynman diagrams with three external legs. Algorithms for their numerical evaluation are introduced and disc…
Influence of Super-Horizon Scales on Cosmological Observables Generated during Inflation
Sabino Matarrese, Marcello A. Musso, Antonio Riotto
Using the techniques of out-of-equilibrium field theory, we study the influence on the properties of cosmological perturbations generated during inflation on observable scales comi…
4-point effective actions in open and closed superstring theory
Osvaldo Chandia, Ricardo Medina
Recently the effective action for the 4-point functions in abelian open superstring theory has been derived, giving an explicit construction of the bosonic and fermionic terms of t…
Nuclear effects in positive pion electroproduction on the deuteron near threshold
L. Levchuk, L. Canton, A. Shebeko
Positive pion electroproduction from the deuteron near threshold has been considered within an approach based on the unitary transformation method. The gauge independence of the tr…
A measurement of the branching fractions of the b-quark into charged and neutral b-hadrons
The DELPHI Collaboration, J. Abdallah
The production fractions of charged and neutral b-hadrons in b-quark events from Z0 decays have been measured with the DELPHI detector at LEP. An algorithm has been developed, base…
On higher spins and the tensionless limit of String Theory
A. Sagnotti, M. Tsulaia
We discuss string spectra in the low-tension limit using the BRST formalism, with emphasis on the role of triplets of totally symmetric tensors and spinor-tensors and their general…
Combination of CDF and D0 Results on W Boson Mass and Width
V. M. Abazov
The results based on 1992-95 data (Run 1) from the CDF and DO experiments on the measurements of the W boson mass and width are presented, along with the combined results. We repor…
Bulk fields with brane terms
F. del Aguila, M. Perez-Victoria, J. Santiago
In theories with branes, bulk fields get in general divergent corrections localized on these defects. Hence, the corresponding brane terms are renormalized and should be included i…
