輕子夸克 的英文怎麼說
中文拼音 [qīngzikuākè]
輕子夸克
英文
leptonic quark-
A quark ( or an antiquark ) from the projectile hadron radiates a virtual photon on impact on the target, the photon subsequently decays into a lepton pair
入射強子中的一個夸克（或反夸克）在靶的作用下輻射出一個虛光子，虛光子再衰變成正反輕子對。The different kinds of quarks or leptons are known technically as flavors.
夸克和輕子的這些個同種類，從技術上看是有特色的。By deep inelastic scattering of leptons on nucleus and nuclear drell - yan processes one can learn the parton densities in nucleus
通過輕子與原子核的深度非彈性散射、核drell - yan過程，可以了解原子核中的夸克?部分子分佈的信息。We obtain a new quark potential from the effective dilaton - gluon - coupling inspired by superstring theory, and by using this static potential, we explore the mechanism of quark confinement through calculations of the spin - average energy levels, the widths of the leptonic decays and radiative transitions for heavy quarkonium. the obtained results are compared with that of the cornell potenial
由規范場理論的超弦理論所激發的伸縮子一膠子有效藕合，給出了一個新的靜態夸克一反夸克勢，討論了此勢模型下重介子的自旋平均能譜、輕子衰變和輻射躍遷寬度，並與cdrn叭勢模型所得到的相應結果作了比較These experimental results show that < q12 > is independent of the dimuon mass and logitudinal momentum, and imply the scattering of the incident quark within the target nucleus. by means of the glauber model, the difference of the mean transverse momentum squared < qt2 > is studied for the dependence of the incident proton energy and nucleus. the theoretical results are in good agreement with the fnal e772 experimental data
本文利用多重散射的glauber模型，討論了入射夸克在原子核中傳播的多重散射效應，給出了兩個不同的核drell - yan過程產生的末態輕子對橫動量平方平均值的差值對入射粒子能量核靶核的依賴性關系，計算結果與e772組的實驗數據符合甚好。In this model, according to the different coupling modes, people had developed several models, i. e., model i, ii, iii, iv
在這個模型中，人們根據_ 1與_ 2與夸克和輕子的不同耦合方式又分成了多種形式的理論模型，即現在所謂的模型， ， ， 。And by deep inelastic scattering of polarized leptons on nucleus and polarized nuclear drell - yan process one can understand polarized parton densities in nucleus more deeply
通過極化的輕子與原子核的深度非彈性散射、極化的核drell - yan過程，可以更深入地了解原子核中的極化夸克?部分子分佈的信息。分享友人
