Confirmation of non-thermal hard X-ray excess in the Coma cluster from two epoch observations
Roberto Fusco-Femiano, Mauro Orlandini, Gianfranco Brunetti +4
We report the hard X-ray spectrum of the Coma cluster obtained using the PDS data of two independent BeppoSAX observations performed with a time interval of about three years. In b…
The role of Compton heating in cluster cooling flows
L. Ciotti, J. P. Ostriker, S. Pellegrini
Recent observations by Chandra and XMM-Newton demonstrate that the central gas in "cooling flow" galaxy clusters has a mass cooling rate that decreases rapidly with decreasing temp…
Free-free absorption effects on Eddington luminosity
L. Ciotti, J. P. Ostriker
In standard treatments the Eddington luminosity is calculated by assuming that the electron-photon cross section is well described by the Thomson cross section which is gray (frequ…
Self-consistent stellar dynamical tori
L. Ciotti, G. Bertin, P. Londrillo
We present preliminary results on a new family of distribution functions that are able to generate axisymmetric, truncated (i.e., finite size) stellar dynamical models characterize…
Geometric phase for mixed states: a differential geometric approach
S. Chaturvedi, E. Ercolessi, G. Marmo +3
A new definition and interpretation of geometric phase for mixed state cyclic unitary evolution in quantum mechanics are presented. The pure state case is formulated in a framework…
W Boson Polarisation at LEP2
The OPAL collaboration, G. Abbiendi
Elements of the spin density matrix for W bosons in e+e- -> W+W- -> qqln events are measured from data recorded by the OPAL detector at LEP. This information is used calculate pola…
2MASS NIR photometry for 693 candidate globular clusters in M31 and the Revised Bologna Catalogue
S. Galleti, L. Federici, M. Bellazzini +2
We have identified in the 2MASS database 693 known and candidate globular clusters in M31. The 2MASS J,H,K magnitudes of these objects have been transformed to the same homogeneous…
The VIRMOS deep imaging survey: III. ESO/WFI deep U-band imaging of the 0226-04 deep field
M. Radovich, M. Arnaboldi, V. Ripepi +14
In this paper we describe the U-band imaging of the F02 deep field, one of the fields in the VIRMOS Deep Imaging Survey. The observations were done at the ESO/MPG 2.2m telescope at…
Numerical evaluation of the general massive 2-loop 4-denominator self-mass master integral from differential equations
M. Caffo, H. Czyz, A. Grzelinska +1
The differential equation in the external invariant p^2 satisfied by the master integral of the general massive 2-loop 4-denominator self-mass diagram is exploited and the expansio…
Measurement of the partial widths of the Z into up- and down-type quarks
The OPAL collaboration, G. Abbiendi
Using the entire OPAL LEP1 on-peak Z hadronic decay sample, Z -> qbarq gamma decays were selected by tagging hadronic final states with isolated photon candidates in the electromag…
Flavour independent search for Higgs bosons decaying into hadronic final states in e+e- collisions
The OPAL collaboration, G. Abbiendi
A search for the Higgsstrahlung process e+e- -> hZ is described, where the neutral Higgs boson h is assumed to decay into hadronic final states. In order to be sensitive to a broad…
Periodic orbit theory of two coupled Tchebyscheff maps
C. P. Dettmann, D. Lippolis
Coupled map lattices have been widely used as models in several fields of physics, such as chaotic strings, turbulence, and phase transitions, as well as in other disciplines, such…
The Canada-UK Deep Submillimetre Survey VIII: Source Identifications in the 3-hour field
Dave Clements, Steve Eales, Kris Wojciechowski +10
We present optical, near-infrared and radio observations of the 3-hour field of the Canada-UK Deep Submillimetre Survey. Of the 27 submillimetre sources in the field, nine have sec…
Search for Colour Singlet and Colour Reconnection Effects in Hadronic Z Decays at LEP
L3 Collaboration
A search is performed in symmetric 3-jet hadronic Z decay events for evidence of colour singlet production or colour reconnection effects. Asymmetries in the angular separation of…
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…
A discontinuous Galerkin formulation for a strain gradient-dependent damage model
G. N. Wells, K. Garikipati, L. Molari
The numerical solution of strain gradient-dependent continuum problems has been dogged by continuity demands on the basis functions. For most commonly accepted models, solutions us…
An increased estimate of the merger rate of double neutron stars from observations of a highly relativistic system
M. Burgay, N. D'Amico, A. Possenti +10
The merger of close binary systems containing two neutron stars should produce a burst of gravitational waves, as predicted by the theory of general relativity. A reliable estimate…
Teleportation on a quantum dot array
F. de Pasquale, G. Giorgi, S. Paganelli
We present a model of quantum teleportation protocol based on a double quantum dot array. The unknown qubit is encoded using a pair of quantum dots, coupled by tunneling, with one…
Excited states NLIE for sine-Gordon model in a strip with Dirichlet boundary conditions
Changrim Ahn, Marco Bellacosa, Francesco Ravanini
We investigate various excited states of Sine-Gordon model on a strip with Dirichlet boundary conditions on both boundaries using a Non Linear Integral Equation (NLIE) approach.
BRST treatment of zero modes for the worldline formalism in curved space
Fiorenzo Bastianelli, Olindo Corradini, Andrea Zirotti
One-loop quantities in QFT can be computed in an efficient way using the worldline formalism. The latter rests on the ability of calculating 1D path integrals on the circle. In thi…
