Search for the decay
A. Lai
A search for the decay has been made using the NA48 detector at the CERN SPS. Using data collected in 1999 during a 40-hour run with a high-intensity beam, an u…
Noncommutative QED and the Lifetimes of Ortho and Para Positronium
Mauro Caravati, Alberto Devoto, Wayne W. Repko
We examine the implications of including corrections associated with the noncommutative extension of quantum electrodynamics - NCQED - to the decays of the ortho and para positroni…
Super-Kamiokande hep neutrino best fit: a possible signal of nonmaxwellian solar plasma
Massimo Coraddu, Marcello Lissia, Giuseppe Mezzorani +1
The Super-Kamiokande best global fit, which includes data from SNO, Gallium and Chlorine experiments, results in a hep neutrino contribution to the signals that, even after oscilla…
Cross sections and single spin asymmetries in hadronic collisions with intrinsic transverse momentum effects
U. D'Alesio, F. Murgia
The role of intrinsic transverse momentum both in unpolarized and polarized processes is discussed. We consider inclusive cross sections for pion production in hadronic collisions…
Single spin asymmetries, unpolarized cross sections and the role of partonic transverse momentum
U. D'Alesio, F. Murgia
Partonic intrinsic transverse momentum can be essential for the explanation of large single spin asymmetries in hadronic reactions in the framework of perturbative QCD. The status…
Tachyons in de Sitter space and analytical continuation from dS/CFT to AdS/CFT
M. Cadoni, P. Carta
We discuss analytic continuation from d-dimensional Lorentzian de Sitter (dS) to d-dimensional Lorentzian anti-de Sitter (AdS) spacetime. We show that AdS, with opp…
Transverse single spin asymmetries in Drell-Yan processes
M. Anselmino, U. D'Alesio, F. Murgia
Recently, it has been shown, contrary to previous beliefs, that the k_T distribution of quarks in a transversely polarized proton can be asymmetric. This ``Sivers effect'' had alre…
Precise measurements of the KS->gamma gamma and KL->gamma gamma decay rates
A. Lai
The KS->gamma gamma decay rate has been measured with the NA48 detector using a high intensity short neutral beam from the CERN SPS. The measured branching ratio BR(KS->gamma gamma…
Two-dimensional gravity with an invariant energy scale and arbitrary dilaton potential
S. Mignemi
We investigate a model of two-dimensional gravity with arbitrary scalar potential obtained by gauging a deformation of de Sitter or more general algebras, which accounts for the ex…
Ultra high energy photon showers in magnetic field:angular distribution of produced particles
Massimo Coraddu, Marcello Lissia, Giuseppe Mezzorani
Ultra high energy (UHE) photons can initiate electromagnetic showers in magnetic field. We analyze the two processes that determine the development of the shower, pair cr…
Two-dimensional gravity with an invariant energy scale
S. Mignemi
We investigate the gauging of a two-dimensional deformation of the Poincare algebra, which accounts for the existence of an invariant energy scale. The model describes 2D dilaton g…
High-energy neutrino conversion into electron-W pair in magnetic field and its contribution to neutrino absorption
Andrea Erdas, Marcello Lissia
We calculate the conversion rate of high-energy neutrinos propagating in constant magnetic field into an electron-W pair (nu -> W + e) from the imaginary part of the neutrino self-…
Non-conventional statistical effects in relativistic heavy-ions collisions
W. M. Alberico, A. Lavagno, P. Quarati
We show that non-conventional statistical effects (due to the presence of long range forces, memory effects, correlations and fluctuations) can be very relevant in the interpretati…
Precise measurement of the decay
A. Lai
The decay rate of $\klpgg$ has been measured with the NA48 detector at the CERN SPS. A total of 2558 $\klpgg$ candidates have been observed with a residual background of 3.2%. The…
A Measurement of the K_S Lifetime
NA48 Collaboration
A measurement of the K_S lifetime is presented using data recorded by the NA48 experiment at the CERN-SPS during 1998 and 1999. The K_S lifetime is derived from the ratio of decay…
New measurements of the and masses
A. Lai, NA48 collaboration
New measurements of the and masses have been performed using decays to 3 with the NA48 detector at the CERN SPS. Using symmetric decays to reduce systematic effects,…
Quantum dilaton gravity as a linear dilaton conformal field theory
M. Cadoni, P. Carta, S. Mignemi
A model of matter-coupled gravity in two dimensions is quantized. The crucial requirement for performing the quantization is the vanishing of the conformal anomaly, which is achiev…
The Cardy-Verlinde formula for 2D gravity
M. Cadoni, P. Carta, S. Mignemi
We discuss the different bounds on entropy in the context of two-dimensional cosmology. We show that in order to obtain well definite bounds one has to use the scale symmetry of th…
Transverse Lambda polarization in inclusive processes
M. Anselmino, D. Boer, U. D'Alesio +1
A formalism proposed to study transverse Lambda polarization in unpolarized hadronic processes, based on a generalized pQCD factorization theorem, is extended to semi-inclusive DIS…
Cosmology of the Jackiw-Teitelboim model
M. Cadoni, S. Mignemi
We investigate the cosmology of the two-dimensional Jackiw-Teitelboim model. Since the matter coupling is not defined uniquely, we consider two possible choices. The dilaton field…
