Analysis of HERA data with a PDF parametrization inspired by quantum statistical mechanics
Marco Bonvini, Franco Buccella, Francesco Giuli +1
We present a determination of the parton distribution functions (PDFs) of the proton from HERA data using a PDF parametrization inspired by a quantum statistical model of the proto…
How is transversity related to helicity for quarks and antiquarks inside the proton?
C. Bourrely, F. Buccella, J. Soffer
We consider the quark and antiquark transversity distributions inside a polarized proton and we study how they are expected to be related to the corresponding helicity distribution…
A Selection Rule for Multiquark Decays
F. Buccella
By assuming SU(6)_cs symmetry for pentaquark decays one finds a selection rule, which strongly reduces the number of states able to decay into a baryon and a meson final state and…
A statistical approach for polarized parton distributions
C. Bourrely, J. Soffer, F. Buccella
A global next-to-leading order QCD analysis of unpolarized and polarized deep-inelastic scattering data is performed with parton distributions constructed in a statistical physical…
Neutrino masses and mixings in SO(10)
M. Abud, F. Buccella, D. Falcone +2
Assuming a Zee-like matrix for the right-handed neutrino Majorana masses in the see-saw mechanism, one gets maximal mixing for vacuum solar oscillations, a very small value for $U_…
Polarized Quarks, Gluons and Sea in Nucleon Structure Functions
C. Bourrely, F. Buccella, O. Pisanti +2
We perform a NLO analysis of polarized deep inelastic scattering data to test two different solutions to the so called spin crisis: one of them based on the axial gluon anomaly and…
SO(10) Unified Theories and Cosmology
F. Buccella, G. Mangano, O. Pisanti +1
We review the status of a class of gauge unified models based on SO(10) group. After a pedagogical introduction to SO(10) gauge theories, we discuss the main phenomenological impli…
A Positive Test for Fermi-Dirac Distributions of Quark-Partons
F. Buccella, I. Dorsner, O. Pisanti +2
By describing a large class of deep inelastic processes with standard parameterization for the different parton species, we check the characteristic relationship dictated by Pauli…
Low x Behaviour of the Isovector Nucleon Polarized Structure Function and the Bjorken Sum Rule
F. Buccella, O. Pisanti, P. Santorelli
The combination g_1^p(x) - g_1^n(x) is derived from SLAC data on polarized proton and deuteron targets, evaluated at Q^2 = 10 GeV^2, and compared with the results of SMC experiment…
Quantum Statistical Parton Distributions and the Spin Crisis
F. Buccella, G. Miele, N. Tancredi
Quantum statistical distributions for the partons provide a fair description of deep inelastic scattering data at and . The study of the polarized structure…
Quarks and Gluons in Nucleon Polarized Structure Functions
C. Bourrely, F. Buccella, O. Pisanti +2
We study the available data in polarized e-p deep inelastic scattering to test two different solutions to the so called spin crisis: one of them based on the axial gluon anomaly an…
Does One Need the Anomaly to Describe the Polarized Structure Functions?
F. Buccella, O. Pisanti, P. Santorelli +1
The SLAC data on the p, d and n polarized structure functions are fairly well reproduced with and without the contribution of the anomaly. The results are compared with a previous…
Fermi-Dirac statistics plus liquid description of quark partons
F. Buccella, G. Miele, G. Migliore +1
A previous approach with Fermi-Dirac distributions for fermion partons is here improved to comply with the expected low behaviour of structure functions. We are so able to get…
Fermi-Dirac Distributions for Quark Partons
C. Bourrely, F. Buccella, G. Miele +4
We propose to use Fermi-Dirac distributions for quark and antiquark partons. It allows a fair description of the -dependence of the very recent NMC data on the proton and neutro…
Majorana Masses for Neutrinos in SO(10)
G. Amelino-Camelia, F. Buccella, L. Rosa
We study the predictions for Majorana masses for neutrinos in SO(10) grandunification models. (This paper precedes and is cited in the article "PROTON DECAY AND NEUTRINO MASSES IN…
Nonleptonic Cabibbo Favoured -Decays and -Asymmetries for Charmed Final Hadron States in Isgur and Wise Theory
F. Buccella, F. Lombardi, G. Miele +1
The Cabibbo allowed non-leptonic -decays in two hadrons are studied, within the factorization hypothesis, in the framework of Isgur and Wise theory for the matrix elements of th…
