Search for Periodic Gravitational Wave Sources with the Explorer Detector
P. Astone
We have developped a procedure for the search of periodic signals in the data of gravitational wave detectors. We report here the analysis of one year of data from the resonant det…
Differential cross section measurement of eta photoproduction on the proton from threshold to 1100 MeV
GRAAL collaboration, F. Renard, M. Anghinolfi +33
The differential cross section for the reaction p(gamma, eta p) has been measured from threshold to 1100 MeV photon laboratory energy. For the first time, the region of the S11(153…
SUSY Ward identities in N=1 SYM theory on the lattice
F. Farchioni, A. Feo, T. Galla +5
The SUSY Ward identities (WIs) for the N=1 SU(2) SUSY Yang Mills theory discretized on the lattice with Wilson fermions (gluinos) are considered. The study is performed in the fram…
Energetic Cosmic Rays observed by the resonant gravitational wave detector NAUTILUS
P. Astone, M. Bassan, P. Bonifazi +19
Cosmic ray showers interacting with the resonant mass gravitational wave antenna NAUTILUS have been detected. The experimental results show large signals at a rate much greater tha…
Lattice hadron matrix elements with the Schroedinger functional: the case of the first moment of non-singlet quark density
M. Guagnelli, K. Jansen, R. Petronzio
We present the results of a non-perturbative determination of the pion matrix element of the twist-2 operator corresponding to the average momentum of non-singlet quark densities.…
On the Multi-Instanton Measure for Super Yang--Mills Theories
Ugo Bruzzo, Francesco Fucito, Alessandro Tanzini +1
In this paper we revisit the arguments that have led to the proposal of a multi-instanton measure for supersymmetric Yang-Mills theories. We then recall how the moduli space of gau…
The Transverse Asymmetry from Quasi-elastic Process and the Neutron Magnetic Form Factor
W. Xu
We have measured the transverse asymmetry from inclusive scattering of longitudinally polarized electrons from polarized 3He nuclei at quasi-elastic kinematics in Hall A at Jeffers…
Type-I strings on magnetised orbifolds and brane transmutation
C. Angelantonj, I. Antoniadis, E. Dudas +1
In the presence of internal magnetic fields, a D9 brane can acquire a D5 (or anti-D5) R-R charge, and can therefore contribute to the corresponding tadpole. In the resulting vacua,…
Study of Coincidences between Resonant Gravitational Wave Detectors
P. Astone, M. Bassan, P. Bonifazi +17
Coincidences are searched with the cryogenic resonant gravitational wave detectors EXPLORER and NAUTILUS, during a period of about six months (2 June-14 December 1998) for a total…
GNO Solar Neutrino Observations: Results for GNOI
GNO Collaboration, M. Altmann, M. Balata +28
We report the first GNO solar neutrino results for the measuring period GNOI, solar exposure time May 20, 1998 till January 12, 2000. In the present analysis, counting results for…
Poincare' Covariant Current Operator and Elastic Electron-Deuteron Scattering in the Front-form Hamiltonian Dynamics
F. M. Lev, E. Pace, G. Salme`
The deuteron electromagnetic form factors, and , and the tensor polarization , are unambiguously calculated within the front-form relativistic Hamilto…
RI/MOM Renormalization Window and Goldstone Pole Contamination
L. Giusti, A. Vladikas
We perform a comparative study of the ratio of lattice (Wilson fermion) renormalization constants Z_P/Z_S, obtained non-perturbatively from the RI/MOM renormalization conditions an…
Instanton Calculus, Topological Field Theories and N=2 Super Yang-Mills Theories
Diego Bellisai, Francesco Fucito, Alessandro Tanzini +1
The results obtained by Seiberg and Witten for the low-energy Wilsonian effective actions of N=2 supersymmetric theories with gauge group SU(2) are in agreement with instanton comp…
Initial operation of the International Gravitational Event Collaboration
G. A. Prodi, I. S. Heng, Z. A. Allen +46
The International Gravitational Event Collaboration, IGEC, is a coordinated effort by research groups operating gravitational wave detectors working towards the detection of millis…
Multi-Instantons, Supersymmetry and Topological Field Theories
D. Bellisai, F. Fucito, A. Tanzini +1
In this letter we argue that instanton-dominated Green's functions in N=2 Super Yang-Mills theories can be equivalently computed either using the so-called constrained instanton me…
Room Temperature Organic Superconductor?
N. Breda, R. A. Broglia, G. Colo` +3
The electron--phonon coupling in fullerene C28 has been calculated from first principles. The value of the associated coupling constant lambda/N(0) is found to be a factor three la…
Open-string models with broken supersymmetry
A. Sagnotti
I review the salient features of three classes of open-string models with broken supersymmetry. These suffice to exhibit, in relatively simple settings, the two phenomena of ``bran…
