The QCD potential
نویسنده
چکیده
The potential between a heavy quark and antiquark has been one of the first quantities to be studied in QCD: it is a privileged object for exploring the interplay of perturbative and non-perturbative QCD and the set in of confinement, and it plays a central role in quarkonium physics [1]. Nowadays, the progress of perturbative and lattice calculations requires an accurate and rigorous definition of the potential in QCD, phenomenological and intuitive characterizations being no longer adequate. So, what is the QCD potential between a quark and antiquark with a large mass m? One may first answer that the potential is the function V into the Schrödinger equation describing the quark-antiquark bound state φ :

بررسی مدلهای گوناگون QCD و مقایسه آنها با نتایج حاصل از نابودی e+e- در انرژی مرکز جرم60GeV
We present the QCD models based on the hadronization of final states of e+e- annihilations, in 60 GeV centre of mass energy in the AMY detector at the KEK collider TRISTAN. To achieve this, we first find the jet axis by using the momentum tensor and diagonilizing it for each event. The models under consideration are the Webber, the Matrix Elements and the Parton Shower. In most cases our resu...

در این مقاله رسانندگی الکتریکی یک سیستم ناپایدار نظریة QCD در دمای پایین بررسی شده است. یک راه مطالعه چنین سیستمهایی، اعمال یک میدان الکتریکی وابسته به زمان و بررسی رفتار زمانی خارج از تعادل سیستم است. اعمال میدان الکتریکی باعث تولید زوجهای کوارک و آنتی کوارک از فاز محبوس QCD و ایجاد یک جریان الکتریکی میشود. با استفاده از رابطة بین شدت میدان الکتریکی اعمال شده و جریان الکتریکی حاصل از آن می...
متن کاملB?J/?(?,K) Decays within QCD Factorization Approach
We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...

In this research, we are going to study the QCD penguin structure and calculate the second order approximation. The amplitude of decays related to QCD penguin in the quark model up to the first and second orders were calculated. We calculated the amplitude of QCD penguin on lowest order of αs for the first order of the decay processes b→qkg→qkqiqj and for the second order of the decay processes...

This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
متن کاملData Envelopment Analysis from simulation on the Lattice QCD using CCR model
One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...
