چکیده
In this article, we investigate the $\cos2\phi_t$ azimuthal asymmetry in $e ~p\rightarrow e ~J/\psi ~Jet~ X$, where $J/\psi$-jet pair is almost back-to-back transverse plane, within framework of generalized parton model(GPM). We use non-relativistic QCD(NRQCD) to calculate $J/\psi$ production amplitude and incorporate both color singlet(CS) octet(CO) contributions asymmetry. estimate using different parameterizations gluon TMDs kinematics that can be accessed at future electron-ion collider (EIC) also impact momentum dependent (TMD) evolution on present coming from states NRQCD.

Jet quenching and high-pT azimuthal asymmetry 1
Jet quenching and high-p T azimuthal asymmetry Abstract The azimuthal anisotropy of high-p T particle production in non-central heavy ion collisions is among the most promising observables of partonic energy loss in an azimuthally non-symmetric volume of quark-gluon plasma. We discuss the implications of nuclear geometry for the models of partonic energy loss in the context of recent RHIC data ...
متن کاملJet asymmetry in high energy diffractive production ∗
We propose the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy diffractive photoproduction as a sensitive test of the interference of the Odderon (C = −) and Pomeron (C = +) exchange amplitudes in QCD. If measured at HERA, this asymmetry could provide the first experimental evidence of the Odderon.
متن کاملPeriodic Gossiping in Back-to-back Trees
The d-ary back-to-back tree of height k, BBT k d , consists of two complete d-ary trees of height k the leaves of which are identiied. For a proper coloring of the edges of BBT k d with c d + 1 colors, we consider periodic gossiping, i.e. full-duplex all-to-all broadcasting in the 1-port model where communication is made on a link of color i at any time (round) i mod c. We present a coloring fo...

Purpose: The aim of this study was to investigate the effect of core stabilization exercises on low back pain and abdominal and back muscle endurance in patients with chronic low back pain caused by disc herniation. Methods: For this purpose, 30 male and female patients with chronic low back pain due to disc herniation (age =48.55 ± 3.35) were divided into experimental and control groups (...
متن کاملAn Efficient Strategy for Power Rating Reduction of Back-to-Back Converters Used in Railway Power Conditioner
One of the most common solutions to deal with the power quality issues of electrical railway systems is employing Railway Power Conditioner (RPC). In the conventional mode of operation, the RPC power rating deployed in every Traction Power Substation (TPS) is significantly large. This paper mainly focuses on the power rating reduction of RPC through presenting a novel combinatorial compensation...
