2000 CKM-Triangle Analysis A Critical Review with Updated Experimental Inputs and Theoretical Parameters
M. Ciuchini, G. D'Agostini, E. Franco +5
Within the Standard Model, a review of the current determination of the sides and angles of the CKM unitarity triangle is presented, using experimental constraints from the measure…
QCD radiative corrections to hadrons
M. Cacciari, V. Del Duca, S. Frixione +1
We compute the order-$\as$ corrections to the total cross section and to jet rates for the process $\epem\to\epem +$ hadrons, where the hadrons are produced through crossed-channel…
The geometry of W3 algebra: a twofold way for the rebirth of a symmetry
G. Bandelloni, S. Lazzarini
The purpose of this note is to show that W3 algebras originate from an unusual interplay between the breakings of the reparametrization invariance under the diffemorphism action on…
The e p -> e' p eta reaction at and above the S11(1535) baryon resonance
The CLAS Collaboration, R. Thompson
New cross sections for the reaction e p -> ep eta are reported for total center of mass energy W = 1.5--1.86 GeV and invariant momentum transfer Q^2 = 0.25--1.5 GeV^2. This large k…
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…
Addendum to "A Phenomenological Description of pi- Delta++ photoproduction and electroproduction in nucleon resonance region"
M. Ripani, V. Mokeev, M. Anghinolfi +8
We acknowledge a paper on the same subject by other authors, that we didn't have the chance to cite in our work. A few comments on the content of the two papers are made.
Pinning of the domain walls of the cluster spin-glass phase in LTT La_{2-x}Ba_xCuO_4
F. Cordero, A. Paolone, R. Cantelli +1
We compare the low frequency (~1 kHz) anelastic spectra of La_{2-x}Sr_xCuO_4 and La_{2-x}Ba_xCuO_4 at x = 0.03 and 0.06 in the temperature region where the freezing into the cluste…
On the f Sum Rule and its Extensions
Rinaldo Cenni
The sum rule is derived in a non-relativistic frame and connected, via Ward Identities, to the low energy Thomson scattering. A generalisation to isospin symmetry in the nuclea…
Stellar models and Hyades: the Hipparcos test
V. Castellani, S. Degl'Innocenti, P. G. Prada Moroni
We compare theoretical stellar models for Main Sequence (MS) stars with the Hipparcos database for the Hyades cluster to give a warning against the uncritical use of available theo…
Contrasting N Delta and N N parity-violating asymmetries in nuclei
P. Amore, R. Cenni, T. W. Donnelly +1
Several perspectives that can be opened by studying the electroexcitation of the delta via parity-violating electron scattering from nuclei are examined, working within the context…
Evolution of truncated moments of singlet parton distributions
Stefano Forte, Lorenzo Magnea, Andrea Piccione +1
We define truncated Mellin moments of parton distributions by restricting the integration range over the Bjorken variable to the experimentally accessible subset x_0 < x < 1 of the…
The general QCD parametrization and the large N(c) description:Some remarks
G. Morpurgo
Stimulated by a recent paper by Buchmann and Lebed,a comparison is presented of the two methods mentioned in the title for treating hadron properties in QCD.Doubts arise on the equ…
Photoproduction of phi(1020) mesons on the proton at large momentum transfer
Te CLAS Collaboration, E. Anciant
The cross section for meson photoproduction on the proton has been measured for the first time up to a four-momentum transfer -t = 4 GeV^2, using the CLAS detector at the Thoma…
Signatures of massive sgoldstinos at hadron colliders
Elena Perazzi, Giovanni Ridolfi, Fabio Zwirner
In supersymmetric extensions of the Standard Model with a very light gravitino, the effective theory at the weak scale should contain not only the goldstino, but also its supersymm…
On the miracle of the Coleman-Glashow and other baryon mass formulas
G. Dillon, G. Morpurgo
Due to a new measurement of the Xi(0) mass,the Coleman-Glashow formula for the baryon octet e.m. masses (derived using unbroken SU(3) is satisfied to an extraordinary level of prec…
Perturbative Beta Function of N=2 Super Yang-Mills Theories
A. Blasi, V. E. R. Lemes, N. Maggiore +4
An algebraic proof of the nonrenormalization theorem for the perturbative beta function of the coupling constant of N=2 Super Yang-Mills theory is provided. The proof relies on a f…

Elvio Di Salvo, Michail P. Rekalo, Egle Tomasi-Gustafsson
The Dalitz distribution and the effective mass spectrum of the lepton pair produced in the decay , as well as the differential cross sections for the crossed…
Phase space observables and isotypic spaces
G. Cassinelli, E. De Vito, A. Levrero +1
We give necessary and sufficient conditions for the set of Neumark projections of a countable set of phase space observable to constitute a resolution of the identity, and we give…
