   Convergence properties of Lévy expansions: implications for Odderon and proton structure

   T. Csörgő🇭🇺 · R. Pasechnik🇸🇪 · A. Ster🇭🇺

   We detail here the convergence properties of a new model-independent imaging method, the Lévy expansion, that seems to play an important role in the analysis of the differential cross section of elastic hadron-hadron scattering. We demonstrate, how our earlier results concerning the Odderon effects in the differential cross-section of elastic proton-proton and proton-antiproton scattering as well as those related to apparent sub-structures inside the protons were obtained in a convergent and stable manner.

   Beam-helicity asymmetries for single-hadron production in semi-inclusive deep-inelastic scattering from unpolarized hydrogen and deuterium targets

   HERMES Collaboration: A. Airapetian🇩🇪 · N. Akopov🇦🇲 · Z. Akopov🇩🇪 · E.C. Aschenauer🇩🇪 · W. Augustyniak🇵🇱 · S. Belostotski🇷🇺 · H.P. Blok🇳🇱 · V. Bryzgalov🇷🇺 · G.P. Capitani🇮🇹 · E. Cisbani🇮🇹 · G. Ciullo🇮🇹 · M. Contalbrigo🇮🇹 and 63 other authors

   A measurement of beam-helicity asymmetries for single-hadron production in deep-inelastic scattering is presented. Data from the scattering of 27.6 GeV electrons and positrons off gaseous hydrogen and deuterium targets were collected by the HERMES experiment. The asymmetries are presented separately as a function of the Bjorken scaling variable, the hadron transverse momentum, and the fractional energy for charged pions and kaons as well as for protons and anti-protons. These asymmetries are also presented as a function of the three aforementioned kinematic variables simultaneously.
