Baryonic hybrids: Gluons as beads on strings between quarks

, 2004
We analyze the ground state of the heavy-quark hybrid system composed of three quarks and a gluon. The known string tension K and approximately-known gluon mass M lead to a precise specification of the long-range non-relativistic part of the potential ...

Pair production of neutralinos via gluon-gluon collisions [PDF]

, 2000
The production of a neutralino pair via gluon-gluon fusion is studied in the minimal supersymmetric model(MSSM) at proton-proton colliders. The numerical analysis of their production rates are carried out in the mSUGRA scenario.

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover

Advanced Science, Volume 12, Issue 31, August 21, 2025.
This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Iterating QCD scattering amplitudes in the high-energy limit

Journal of High Energy Physics, 2018
We analyse the high-energy limit of the gluon-gluon scattering amplitude in QCD, and display an intriguing relation between the finite parts of the one-loop gluon impact factor and the finite parts of the two-loop Regge trajectory.

A Phenomenological Analysis of Gluon Mass Effects in Inclusive Radiative Decays of the $\rm{J/\psi}$ and $\Upsilon

, 2001
The shapes of the inclusive photon spectra in the processes $\Jp \to \gamma X$ and $\Up \to \gamma X$ have been analysed using all available experimental data.

Higgs production in hadron collisions: soft and virtual QCD corrections at NNLO [PDF]

, 2001
We consider QCD corrections to Higgs boson production through gluon-gluon fusion in hadron collisions. Using the recently evaluated two-loop amplitude for this process and the corresponding factorization formulae for soft-gluon bremsstrahlung at O ...

Gluon–gluon antenna functions from Higgs boson decay

Physics Letters B, 2005
Antenna functions describe the infrared singular behaviour of colour-ordered QCD matrix elements due to the emission of unresolved partons inside an antenna formed by two hard partons. In this paper, we show that antenna functions for hard gluon-gluon pairs can be systematically derived from the effective Lagrangian describing Higgs boson decay into ...

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

Contributions to Plasma Physics, Volume 65, Issue 7, August 2025.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

QCD resummation in hard diffractive dijet production at the electron-ion collider

Physics Letters B, 2020
Diffractive dijet production at the electron-ion collider (EIC) has been proposed to study the gluon Wigner distribution at small-x. We investigate the soft gluon radiation associated with the final state jets and an all order resummation formula is ...

MHV gluon scattering amplitudes from celestial current algebras

Journal of High Energy Physics, 2021
We show that the Mellin transform of an n-point tree level MHV gluon scattering amplitude, also known as the celestial amplitude in pure Yang-Mills theory, satisfies a system of (n−2) linear first order partial differential equations corresponding to (n ...
