Study of the resummation of chiral logarithms in the
From the properties of analyticity and unitarity it has been recently obtained an exponentiated expression for the pion form factor. In this work I show the validity of this expression comparing its order p6 term with the one exactly calculated in ChPT. PACS numbers: 14.40.Aq, 13.40.Gp, 13.60.Fz, 12.39.Fe
متن کاملResummation of Large Logarithms within the Method of Effective Charges
We show how the resummation of large logarithms can be incorporated into the method of effective charges. As an example, we apply this approach to the event shape variables thrust and heavy-jet mass in ee annihilation. We find that, although the resummation creates problems with the behaviour of the effective charge in the 2-jet limit, smaller power corrections are required to fit the data comp...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
Resummation of non-global logarithms at finite Nc
In the context of inter-jet energy flow, we present the first quantitative result of the resummation of non-global logarithms at finiteNc. This is achieved by refining Weigert’s approach in which the problem is reduced to the simulation of associated Langevin dynamics in the space of Wilson lines. We find that, in e+e− annihilation, the exact result is rather close to the result previously obta...
متن کاملResummation of double logarithms in electroweak high energy processes
At future linear e+e− collider experiments in the TeV range, Sudakov double logarithms originating from massive boson exchange can lead to significant corrections to the cross sections of the observable processes. These effects are important for the high precision objectives of the Next Linear Collider. We use the infrared evolution equation, based on a gauge invariant dispersive method, to obt...
