光阵面哈密顿方法中的扭曲三分布f_ \perp(x,k^ \perp)

Twist Three Distribution f_\perp(x,k^\perp) in Light-front Hamiltonian Approach

A. Mukherjee, R. Korrapati

摘要:

计算了非极化半包容深度非弹性散射中对Cahn效应有贡献的扭转三分布f_ \perp(x,k^ \perp).在微扰理论中,我们采用光阵面哈密顿方法,将态取为一圈处的缀饰夸克。“真正的扭曲三”的贡献来自夸克-胶子相互作用的运营商的一部分,并明确计算。将f_ \perp(x,k^ \perp)与f_1(x,k^ \perp)进行比较。

英文摘要:

We calculate the twist three distribution f_\perp(x,k^\perp) contributing to Cahn effect in unpolarized semi-inclusive deep inelastic scattering. We use light-front Hamiltonian technique and take the state to be a dressed quark at one loop in perturbation theory. The 'genuine twist three' contribution comes from the quark-gluon interaction part in the operator and is explicitly calculated. f_\perp(x,k^\perp) is compared with f_1(x,k^\perp).
