Surprises from the Resolution of Operator Mixing in N = 4 SYM
Massimo Bianchi, Giancarlo Rossi, Yassen S. Stanev
We reexamine the problem of operator mixing in N = 4 SYM. Particular attention is paid to the correct definition of composite gauge invariant local operators, which is necessary fo…
Twisted-mass lattice QCD with mass non-degenerate quarks
R. Frezzotti, G. C. Rossi
The maximally twisted lattice QCD action of an doublet of mass degenerate Wilson quarks gives rise to a real positive fermion determinant and it is invariant under the pr…
Electromagnetic form factor of the pion in the space- and time-like regions within the front-form dynamics
J. P. B. C. de Melo, T. Frederico, E. Pace +1
The pion electromagnetic form factor is calculated in the space- and time-like regions from -10 up to 10 , within a front-form model. The dressed photon vert…
Results from DAMA/NaI and perspectives for DAMA/LIBRA
R. Bernabei, P. Belli, F. Cappella +9
The about 100 kg highly radiopure NaI(Tl) set-up of the DAMA project (DAMA/NaI) took data over seven annual cycles up to July 2002 and has achieved results on various rare processe…
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…
Superlocalization formulas and supersymmetric Yang-Mills theories
Ugo Bruzzo, Francesco Fucito
By using supermanifold techniques we prove a generalization of the localization formula in equivariant cohomology which is suitable for studying supersymmetric Yang-Mills theories…
Possible evidence of extended objects inside the proton
R. Petronzio, S. Simula, G. Ricco
Recent data on the Nachtmann moments of the unpolarized proton structure function F2p, obtained at low momentum transfer with the CLAS detector at Jefferson Lab, are interpreted in…
New Results on Holographic Three-Point Functions
Massimo Bianchi, Wolfgang Mück, Maurizio Prisco
We exploit a gauge invariant approach for the analysis of the equations governing the dynamics of active scalar fluctuations coupled to the fluctuations of the metric along hologra…
Non-perturbative renormalization of moments of parton distribution functions
A. Shindler, M. Guagnelli, K. Jansen +3
We compute non-perturbatively the evolution of the twist-2 operators corresponding to the average momentum of non-singlet quark densities. The calculation is based on a finite-size…
Chirally improving Wilson fermions
R. Frezzotti, G. C. Rossi
It is possible to improve the chiral behaviour and the approach to the continuum limit of correlation functions in lattice QCD with standard and twisted Wilson fermions by taking a…

P. Dimopoulos, J. Heitger, C. Pena +2
We present some preliminary results for at , using the twisted mass QCD formalism for the computation of bare matrix elements of the operator. The main advantag…
Quark bilinear step scaling functions and their continuum limit extrapolation
M. Guagnelli, J. Heitger, C. Pena +1
Some new results on nonperturbative renormalisation of quark bilinears in quenched QCD with Schroedinger Functional techniques are presented. Special emphasis is put on a study of…
Pion parton distribution functions from lattice QCD
I. Wetzorke, M. Guagnelli, K. Jansen +3
We report on recent results for the pion matrix element of the twist-2 operator corresponding to the average momentum of non-singlet quark densities. For the first time finite volu…
Measurement of Inclusive f_1(1285) and f_1(1420) Production in Z Decays with the DELPHI Detector
The DELPHI Collaboration, J. Abdallah
DELPHI results are presented on the inclusive production of two (K Kbar pi)^0 states in the mass region 1.2-1.6 GeV/c^2 in hadronic Z decays at LEP I. The measured masses (widths)…
Non-Integrability of a weakly integrable Hamiltonian system
Giuseppe Pucacco, Kjell Rosquist
The geometric approach to mechanics based on the Jacobi metric allows to easily construct natural mechanical systems which are integrable (actually separable) at a fixed value of t…
Increasing the bandwidth of resonant gravitational antennas: The case of Explorer
P. Astone, D. Babusci, M. Bassan +22
Resonant gravitational wave detectors with an observation bandwidth of tens of hertz are a reality: the antenna Explorer, operated at CERN by the ROG collaboration, has been upgrad…
Dark Matter search
R. Bernabei, P. Belli, F. Cappella +9
Main arguments on the Dark Matter particle direct detection approach are addressed on the basis of the work and of the results of the about 100 kg highly radiopure NaI(Tl) DAMA exp…

Burkhard Eden
We show how to determine the lowest order mixing of all scalar with two-fermion two impurity BMN operators in the antisymmetric representation of SO(4). Differentiation on harmonic…
Intermittency in Turbulence: computing the scaling exponents in shell models
Roberto Benzi, Luca Biferale, Mauro Sbragaglia +1
We discuss a stochastic closure for the equation of motion satisfied by multi-scale correlation functions in the framework of shell models of turbulence. We give a systematic proce…
Heavy--light decay constants in the continuum limit of quenched lattice QCD
G. M. de Divitiis, M. Guagnelli, F. Palombi +2
We compute the decay constants for the heavy--light pseudoscalar mesons in the quenched approximation and continuum limit of lattice QCD. Within the Schrodinger Functional framewor…
