Mass and charge identification of fragments detected with the Chimera Silicon-CsI(Tl) telescopes
N. Le Neindre, for REVERSE collaboration
Mass and charge identification of charged products detected with Silicon-CsI(Tl) telescopes of the Chimera apparatus is presented. An identification function, based on the Bethe-Bl…
Search for Leptoquarks in Electron-Photon Scattering at sqrt(s_ee) up to 209 GeV at LEP
The OPAL collaboration, G. Abbiendi
Searches for first generation scalar and vector leptoquarks, and for squarks in R-parity violating SUSY models with the direct decay of the squark into Standard Model particles, ha…
Deep HST-WFPC2 photometry of NGC 288. I. Binary Systems and Blue Stragglers
M. Bellazzini, F. Fusi Pecci, M. Messineo +2
We present the first results of a deep WFPC2 photometric survey of the loose galactic globular cluster NGC 288. The fraction of binary systems is estimated from the color distribut…
Effects of neutrino oscillations on the supernova signal in LVD
M. Aglietta, P. Antonioli, G. Bari +21
We study the impact of neutrino oscillations on the supernova neutrino signal in the Large Volume Detector (LVD). The number of expected events for a galactic supernova (D=10 kpc)…
The AGN content of hard X-ray surveys
A. Comastri, C. Vignali, M. Brusa
Multiwavelength observations of the hard X-ray selected sources discovered by BeppoSAX, Chandra and XMM-Newton surveys have significantly improved our knowledge of the AGN populati…
Large Gas Disks in Radiogalaxies
R. Morganti, T. A. Oosterloo, S. Tinti +3
Large-scale (up to 100 kpc) HI structures have been found in three radio galaxies using the WSRT and the VLA. In one case, the HI has been detected in emission while in the other t…
The HST survey of the B2 sample of radio-galaxies: optical nuclei and the FRI/BL Lac unified scheme
A. Capetti, A. Celotti, M. Chiaberge +4
We examine the optical properties of the nuclei of low luminosity radio-galaxies using snapshot HST images of the B2 sample. In agreement with the results obtained from the analysi…
Galaxy merging and the Fundamental Plane of elliptical galaxies
Carlo Nipoti, Pasquale Londrillo, Luca Ciotti
We present preliminary results of numerical simulations of dissipationless merging of stellar systems, aimed at exploring the consequences of merging between gas free, spheroidal s…
The Two-Loop QCD Matrix Element for Jets
L. W. Garland, T. Gehrmann, E. W. N. Glover +2
We compute the virtual QCD corrections to the matrix element arising from the interference of the two-loop with the tree-level amplitude and fr…
The Bologna Key Project on Omega Cen
F. R. Ferraro, E. Pancino, M. Bellazzini
In this contribution we schematically summarize a number of ongoing, coordinated spectro-photometric projects devoted to the study of the stellar population properties in Omega Cen…
The Multiple Stellar Populations in Omega Centauri
Elena Pancino
In this contribution I am going to present some preliminary results of a high-resolution spectroscopic campaign focussed on the most metal rich red giant stars in Omega Cen. This s…
Ornstein-Zernike Theory for the finite range Ising models above T_c
M. Campanino, D. Ioffe, Y. Velenik
We derive precise Ornstein-Zernike asymptotic formula for the decay of the two-point function in the general context of finite range Ising type models on Z^d. The proof relies in a…
Measurement of the Total Cross Section and Differential Cross Section in Collisions at TeV
The CDF collaboration
We present measurements of the B+ meson total cross section and differential cross section . The measurements use a pb^{-1} sample of collisions at $…
Energy-Momentum Tensor of Field Fluctuations in Massive Chaotic Inflation
F. Finelli, G. Marozzi, G. P. Vacca +1
We study the renormalized energy-momentum tensor (EMT) of the inflaton fluctuations in rigid space-times during the slow-rollover regime for chaotic inflation with a mass term. We…
Optical identifications of High Frequency Peakers
D. Dallacasa, R. Falomo, C. Stanghellini
We present CCD observations of 13 objects from a complete sample of 55 bright High Frequency Peaker (HFP) radio sources, and provide optical identification for 12 of them. Images i…
Numerical Evaluation of Two-Dimensional Harmonic Polylogarithms
T. Gehrmann, E. Remiddi
The two-dimensional harmonic polylogarithms $\G(\vec{a}(z);y)$, a generalization of the harmonic polylogarithms, themselves a generalization of Nielsen's polylogarithms, appear in…
Search for Doubly Charged Higgs Bosons with the OPAL detector at LEP
The OPAL collaboration, G. Abbiendi
A search for pair-produced doubly charged Higgs bosons has been performed using data samples corresponding to an integrated luminosity of about 614 pb-1 collected with the OPAL det…
Nuclear and global X-ray properties of LINER galaxies: Chandra and BeppoSAX results for Sombrero and NGC 4736
S. Pellegrini, G. Fabbiano, F. Fiore +2
We report on the 0.1--100 keV BeppoSAX observations of two nearby LINER galaxies, Sombrero and NGC 4736. Chandra ACIS-S observations supplement this broad-beam spectral study with…
Spontaneous CPT asymmetry of the Universe
A. A. Andrianov, P. Giacconi, R. Soldati
The extended QED with renormalizable interactions breaking the Lorentz and CPT symmetry is considered and the phenomenological consequences of such a symmetry breaking are illumina…
