Glueball masses in quantum chromodynamics [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1997
We review the recent glueball mass calculations using an efficient method for solving the Schr dinger equation order by order with a scheme preserving the continuum limit. The reliability of the method is further supported by new accurate results for (1+1)-dimensional $ $ models and (2+1)-dimensional non-abelian models.

Multiparticle production and quantum chromodynamics [PDF]

open access: yes, 2002
The theory of strong interactions, quantum chromodynamics (QCD), is quite successful in the prediction and description of main features of multiparticle production processes at high energies.

Persistent Challenges of Quantum Chromodynamics [PDF]

open access: yes, 2006
Unlike some models whose relevance to Nature is still a big question mark, Quantum Chromodynamics will stay with us forever. Quantum Chromodynamics (QCD), born in 1973, is a very rich theory supposed to describe the widest range of strong interaction ...

New Approach to Investigation of Nuclei

open access: yesEPJ Web of Conferences, 2014
We demonstrate that the sum rules of quantum chromodynamics provide a consistent formalism for solving various problems of nuclear physics.

The Three Loop Two-Mass Contribution to the Gluon Vacuum Polarization [PDF]

open access: yes, 2017
We calculate the two-mass contribution to the 3-loop vacuum polarization of the gluon in Quantum Chromodynamics at virtuality $p^2 = 0$ for general masses and also present the analogous result for the photon in Quantum Electrodynamics.Comment: 5 pages ...

Investigation of the internal structure of the deuteron against the background of two-photon exchange effects in elastic electron-deuteron scattering [PDF]

open access: yesЯдерна фізика та енергетика
This work aims to investigate the simultaneous influence of two-photon effects in quantum electrodynamics and logarithmic corrections in quantum chromodynamics on certain observable experimental quantities (structure functions A(Q2) and B(Q2) in elastic ...

Free energy expansions of a conditional GinUE and large deviations of the smallest eigenvalue of the LUE

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 12, Page 2247-2304, December 2025.
Abstract We consider a planar Coulomb gas ensemble of size N$N$ with the inverse temperature β=2$\beta =2$ and external potential Q(z)=|z|2−2clog|z−a|$Q(z)=|z|^2-2c \log |z-a|$, where c>0$c>0$ and a∈C$a \in \mathbb {C}$. Equivalently, this model can be realised as N$N$ eigenvalues of the complex Ginibre matrix of size (c+1)N×(c+1)N$(c+1) N \times (c+1)

Discoveries in ultra-peripheral collisions: Past, present, future [PDF]

open access: yesEPJ Web of Conferences
Ultra-relativistic heavy-ion collisions produce extremely strong electromagnetic field which provide a uniquely intense and energetic source of photons. The photons manifest from such ultra-Lorentz contracted electromagnetic fields have, in recent years,
