Gluons in glueballs: spin or helicity?

, 2008
peer reviewedIn the past decade, lattice QCD has been able to compute the low-lying glueball spectrum with accuracy. Like other effective approaches of QCD, potential models still have difficulties to cope with gluonic hadrons.

Gluons: Connecting Software Components: working paper

, 1991
This paper presents an approach to software construction that relies on the connection of reusable components. The approach is derived from the observation that a design framework plays a central role in the reuse process in the sense that both the ...

Marginality from leading soft gluons

Journal of High Energy Physics
Marginal operators in a d-dimensional conformal field theory (CFT), those with conformal dimension ∆ = d, give us information about the space of related theories.

DGLAP evolution for DIS diffraction production of high masses

European Physical Journal C: Particles and Fields, 2018
In this paper we develop the DGLAP evolution for the system of produced gluons in the process of diffractive production in DIS, directly from the evolution equation in Color Glass Condensate approach.

Gluon emission in Quark-Gluon Plasma

, 2010
Gluon radiation is an important mechanism for parton energy loss as the parton traverses the quark gluon plasma (QGP) medium. We studied the gluon emission in QGP using AMY formalism. In the present work, we obtained gluon emission amplitude {\bf F}({\bf h},p,k) function, which is a solution of the integral equations describing gluon radiation ...

On possible contribution of partons’ orbital momentum to the proton spin

EPJ Web of Conferences, 2017
Virtual parton excitations of proton achieve status of real particles after transition into the infinite momentum frame. In particular, QCD evolution of them should respect the conservation laws which in turn should be a necessary consequence of symmetry

Effective potential between two gluons from the scalar glueball

, 2007
Starting from the 0++ glueball mass and wave function computed from lattice QCD, we compute the local potential between two constituent gluons. Since the properties of constituent gluons are still a matter of research, we allow for them to be either ...

Inhomogeneous confinement and chiral symmetry breaking induced by imaginary angular velocity

Physics Letters B
We investigate detailed properties of imaginary rotating matter with gluons and quarks at high temperature. Previously, we showed that imaginary rotation induces perturbative confinement of gluons at the rotation center.

Towards the next QCD Frontier with the Electron Ion Collider

EPJ Web of Conferences, 2016
In this talk, we argue that the proposed Electron-Ion Collider (EIC) with its unique capability to collide polarized electrons with polarized protons and light ions at unprecedented luminosity, and with heavy nuclei at high energy, will be the most ...
