The former is within perturbative quantum chromodynamics domain and the latter is within non - perturbative quantum chromodynamics domain 前者屬于微擾量子色動(dòng)力學(xué)范疇,后者屬于非微擾量子色動(dòng)力學(xué)范疇。
With the development of quantum chromodynamics ( qcd ) , people started to investigate the origin and nature of the pomeron from qcd viewpoint 隨著量子色動(dòng)力學(xué)( qcd )理論的發(fā)展,人們開(kāi)始用qcd的觀點(diǎn)去探討pomeron本源和性質(zhì)。
In this thesis , we derive a new quark potential by constructing the effective theory of quantum chromodynamics ( qcd ) with dilation inspired by superstring theory and study this new quark potential in heavy mesons sector 本文構(gòu)建了一種有伸縮子( dilaton )的量子色動(dòng)力學(xué)( qcd )有效理論,得到了一種新的夸克相互作用勢(shì)。
The huge energy - momentum of particles can be transformed into thermal energy by accelerator experiment at high energy to study perturbative vacuum of quantum chromodynamics and determine the signal of quark - gluon plasma 在實(shí)驗(yàn)上,人們通過(guò)相對(duì)論性重離子碰撞實(shí)驗(yàn)把巨大的動(dòng)能轉(zhuǎn)化為熱能,來(lái)研究量子色動(dòng)力學(xué)的微擾真空及其所預(yù)言的夸克?膠子等離子體。
At the time , the theory was regarded as a failure ; it did not achieve its goal of explaining the atomic nucleus , and veneziano soon shifted his attention to quantum chromodynamics , to which he made major contributions 當(dāng)時(shí),這個(gè)理論被認(rèn)為是失敗的;它并沒(méi)有達(dá)成解釋原子核物理的目標(biāo),而維納齊亞諾很快就把注意力轉(zhuǎn)移到量子色動(dòng)力學(xué),并對(duì)其做出了主要的貢獻(xiàn)。
One of the focuses in investigating the high energy heavy - ion collisions is to explore the existence and the properties of quark - gluon - plasraa ( qgp ) which is predicted by the strong interaction theory - quantum chromodynamics ( qcd ) 探尋強(qiáng)相互作作理論?量子色動(dòng)力學(xué)( qcd )所預(yù)言的夸克膠子等離子體( qgp )的信號(hào)及相變性質(zhì)( ? )直是高能核?核碰撞實(shí)驗(yàn)的重要目標(biāo)之一。
Since quantum chromodynamics ( qcd ) is nonperturbative in the infrared region as the basic theory of strong interaction , the potential model as one of various models inspired by qcd has been developed to explain the properties of hadron 目前,由于作為強(qiáng)相互作用基本理論的量子色動(dòng)力學(xué)( qcd )在低能區(qū)(大距離)的非微擾效應(yīng),各種qcd激發(fā)的模型一直被發(fā)展來(lái)解釋強(qiáng)子的性質(zhì)。
The investigation of excited baryons is very important in understanding the internal structure of baryon and the strong interaction in the nonperturbative quantum chromodynamics ( npqcd ) regime . however , there was not much progress on the baryon spectroscopy data since the late 1970 ' s 核子激發(fā)態(tài)的研究對(duì)我們認(rèn)識(shí)物質(zhì)微觀結(jié)構(gòu)和強(qiáng)相互作用性質(zhì)有重要意義,目前重子譜的研究對(duì)人類(lèi)認(rèn)識(shí)物質(zhì)微觀結(jié)構(gòu)起著非常的作用。
a theory of strong interactions between elementary particles (including the interaction that binds protons and neutrons in the nucleus); it assumes that strongly interacting particles (hadrons) are made of quarks and that gluons bind the quarks together 同義詞:QCD,
百科解釋
In theoretical physics, quantum chromodynamics (QCD) is a theory of the strong interaction (color force), a fundamental force describing the interactions between quarks and gluons which make up hadrons (such as the proton, neutron or pion). It is the study of the SU(3) Yang?Mills theory of color-charged fermions (the quarks).
