A Possible Signal of Six-Quark Clusters in Deuteron Electrodisintegration

Abstract

Deuteron electrodisintegration cross section in threshold region has been calculated by using the Kisslinger's hybrid quark-hadron model, including isoscalar MEC. The appearance of the second maximum can be explained by the dependence of cross section on , and may be the signal of six-quark clusters.

The Effects of Isoscalar MEC and Six-Quark Cluster on W 1 / W 2 of the Deuteron

“…Based on it, a number of works have been carried out, and can successfully explain experiments. Previous researches on elastic e-d scattering' [8][9][10] ! an d deuteron electrodisintegration' 7 ' show that sixquark clusters have large effect in these ones.…”

“…an d deuteron electrodisintegration' 7 ' show that sixquark clusters have large effect in these ones. Isoscalar MEC takes an important role in elastic e-d scattering,' 10 ' but contributes little to the cross section of deuteron electrodisintegration because of large scattering angle.' 11 ' However, the ratio of inelastic deuteron structure function Wi/W 2 does not depend on scattering angle, and it should be more suitable for investigating isoscalar MEC than cross section.…”

“…In this paper, we shall use the theory of Refs [7] and [11], including isoscalar meson exchange current, to calculate W1/W2 and to study the roles of isoscalar MEC and six-quark clusters.…”
