OPE, Heavy-Quark Mass, and Heavy-Meson Decay Constants from QCD Sum Rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We present a sum-rule extraction of the decay constants of heavy-light mesons from the two-point correlator of pseudoscalar currents. To this end, we compare the perturbative expan…
The deuteron structure function F2 with CLAS
M. Osipenko, G. Ricco, S. Simula +3
The inclusive, inelastic eD scattering cross section has been measured with the CLAS detector in Hall B of the Thomas Jefferson National Accelerator Facility (TJNAF). Combining the…
Global Analysis of Data on the Proton Structure Function g1 and Extraction of its Moments
M. Osipenko, S. Simula, W. Melnitchouk +7
Inspired by recent measurements with the CLAS detector at Jefferson Lab, we perform a self-consistent analysis of world data on the proton structure function g1 in the range 0.17 <…
Higher twist analysis of the proton g_1 structure function
M. Osipenko, W. Melnitchouk, S. Simula +6
We perform a global analysis of all available spin-dependent proton structure function data, covering a large range of Q^2, 1 < Q^2 < 30 GeV^2, and calculate the lowest moment of t…
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…
End-point singularities of Feynman graphs on the light cone
D. Melikhov, S. Simula
We show that some Lorentz components of the Feynman integrals calculated in terms of the light-cone variables may contain end-point singularities which originate from the contribut…
