Neutral pion electroproduction off deuterium
Threshold neutral pion electroproduction on the deuteron is studied in the framework of baryon chiral perturbation theory at next-to-leading order in the chiral expansion. To this order in small momenta, the amplitude is finite and a sum of twoand three-body interactions with no undetermined parameters. We calculate the S-wave multipoles for threshold production and the deuteron S-wave cross se...

Threshold neutral pion electroproduction on the deuteron is studied in the framework of baryon chiral perturbation theory at next–to–leading order in the chiral expansion. To this order in small momenta, the amplitude is finite and a sum of two– and three–body interactions with no undetermined parameters.

متن کاملNear threshold neutral pion electroproduction on deuterium in chiral perturbation theory
Near threshold neutral pion electroproduction on the deuteron is studied in the framework of baryon chiral perturbation theory at next–to–leading order in the chiral expansion. We develop the multipole decomposition for pion production off spin-1 particles appropriate for the threshold region. The existing data at photon virtuality k = −0.1GeV can be described satisfactorily. Furthermore, the p...
متن کاملNeutral-pion electroproduction on the proton near threshold.
The neutral pion electroproduction on the proton is considered in the framework phenomenological model based on the PCAC, current algebra with hard pions and chiral symmetry breaking interaction. The swave differential cross-section of the electroproduction of neutral pions off protons near the threshold is predicted as function photon momentum transfer squared k2 . The swave multipoles ReE0+ a...
متن کامل0 Twist - three analysis of photon electroproduction off pion
Twist-three analysis of photon electroproduction off pion. Abstract We study twist-three effects in spin, charge, and azimuthal asymmetries in deeply virtual Compton scattering off a spin-zero target. Power suppressed contributions generate a new azimuthal angle dependence in the cross section, not present in the leading twist approximation. On the other hand the structures induced by the latte...
