Pion Electroproduction Using Clas

چکیده
Measurements of the p(e;e p)πo reaction in the ∆(1232) resonance region have been performed with the CLAS detector at Jefferson Lab using beam energies of 1.645 and 2.445 GeV. Cross sections were measured over a range of four-momentum transfer Q2= 0.4-1.8 (GeV/c)2. Decay angular distributions in the πo p center-of-mass were obtained with full coverage in cosθ π and φ π. This permits the extraction of the structure functions σT + εLσL,σTT and σLT and their partial wave decomposition. Results are shown for the Q2 and W dependence of the transverse electric and scalar/longitudinal multipole ratios E1+=M1+ and S1+=M1+.

Radiative Corrections for Deuteron Electrodisintegration
Full exclusive calculations of radiative corrections for the d(e, e′p)n and d(e, e′n)p reactions have been performed using a code originally written and tested for pion electroproduction. We find significant differences between radiative corrections calculated with this method and a Schwinger calculation. The program can be obtained from a website referenced in this CLAS-Note.
متن کاملSingle pion electro– and neutrinoproduction on heavy targets
We present a calculation of single pion electroproduction cross sections on heavy targets in the kinematic region of the ∆(1232) resonance. Final state interactions of the pions are taken into account using the pion multiple scattering model of Adler, Nussinov and Paschos (ANP model). For electroproduction and neutral current reactions we obtain results for carbon, oxygen, argon and iron target...
متن کاملPion charge radius from charged pion electroproduction
We analyze a low-energy theorem of threshold pion electroproduction which allows one to determine the charge radius of the pion. We show that at the same order where the radius appears, pion loops induce a correction to the momentum dependence of the longitudinal dipole amplitude L01 (2) . This model-independent correction amounts to an increase of the pion charge radius squared from the electr...
متن کاملPion electroproduction , PCAC , chiral Ward identities , and the axial form factor revisited
We re-investigate Adler’s PCAC relation in the presence of an external electromagnetic field within the framework of QCD coupled to external fields. We discuss pion electroproduction within a tree-level approximation to chiral perturbation theory and explicitly verify a chiral Ward identity referred to as the Adler-Gilman relation. We critically examine soft-momentum techniques and point out ho...
متن کاملAzimuthal Asymmetries in Inclusive Single Pion Electroproduction
The leading and sub-leading order results for pion electroproduction in polarized and unpolarized semi-inclusive deep-inelastic scattering, are considered putting emphasis on transverse momentum dependent effects appearing in azimuthal asymmetries. In particular the spin-dependent (single, double) and spin-independent asymmetries of the distributions in the azimuthal angle φ of the pion related...
