Medium-induced coherent gluon radiation for 2 → 2 processes with general kinematics [PDF]

open access: yesEPJ Web of Conferences
High-energy proton-nucleus (pA) collisions offer valuable insight into the role of cold nuclear matter effects in hadron production. In particular, multiple rescatterings of an incoming parton by the nuclear target are known to induce the radiation of ...

Lattice QCD Analysis for Gluons [PDF]

open access: yes, 2009
Nonperturbative properties of gluons are studied in SU(3) lattice QCD at the quenched level. The first subject is a functional-form analysis of the gluon propagator $D_{\mu\nu}^{ab}(x)$ in the Landau gauge.

The gluon form factor to higher orders: Gluon-gluon annihilation at small Qt

open access: yesPhysics Letters B, 1988
Abstract We study the region of small transverse momenta in the dynamics of the gluon-gluon annihilation channel. This is done by evaluating the gluon form factor at the single non-leading infrared and collinear logarithmic accuracy to all orders in α s . An explicit expression for the gluon form factor is obtained.

Marginality from leading soft gluons

open access: yesJournal 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.

Long-lived HNLs via ALP portal at the LHC

open access: yesJournal of High Energy Physics
Heavy neutral leptons (HNLs) and axion-like particles (ALPs) are both considered well-motivated candidates for beyond the standard model (BSM) physics. If ALPs with sizable couplings to gluons exist, they will be abundantly produced at the LHC. Therefore,

DGLAP evolution for DIS diffraction production of high masses

open access: yesEuropean 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 condensate and the effective gluon mass

open access: yesZeitschrift f�r Physik C Particles and Fields, 1987
Using massive gauge invariant QCD we show explicity how power like corrections to\(\Pi _{\mu v} \left( q \right) = i\int {dx} e^{iq'x} \left\langle {0\left| {j_\mu ^{em} \left( x \right)\bar j_v^{em} \left( 0 \right)} \right|0} \right\rangle \) arise.

Inhomogeneous confinement and chiral symmetry breaking induced by imaginary angular velocity

open access: yesPhysics 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.

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

open access: yesEPJ 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
