We report on the first results of a sensitive search for scalar coupling of photons to a light neutral boson in the mass range of approximately 1.0 milli-electron volts and coupling strength greater...
Quark helicity flip and the transverse spin dependence of inclusive DIS (2007)
Afanasev, A., Strikman, M., Weiss, C.
Inclusive DIS with unpolarized beam exhibits a subtle dependence on the transverse target spin, arising from the interference of one-photon and two-photon exchange amplitudes in the cross section. We...
Transverse target spin asymmetry in inclusive DIS with two-photon exchange (2007)
Afanasev, A., Strikman, M., Weiss, C.
We study the transverse target spin dependence of the cross section for inclusive electron-nucleon scattering with unpolarized beam. Such dependence is absent in the one-photon exchange approximation...
