Heavy-heavy and heavy-light quarks interactions generated by QCD vacuum

open access: yesEPJ Web of Conferences, 2017
The QCD vacuum is populated by instantons that correspond to the tunneling processes in the vacuum. This mechanism creates the strong vacuum gluon fields.

Structure Formation in Dairy Cheese and Plant‐Based Cheese Analogues: A Review

open access: yesSustainable Food Proteins, Volume 4, Issue 3, September 2026.
In this review, structure formation in dairy cheese and plant‐based cheese analogues is analyzed following a multi‐length scale perspective. Particular emphasis is placed on the distinction between bottom‐up assembly, characteristic of natural dairy cheese, and top‐down structuring, typical of processed cheese and cheese analogues.

Meson spectrum in SU(N) gauge theories with quarks in higher representations: A check of Casimir scaling hypothesis

open access: yesResults in Physics, 2020
Gauge theories with gauge group SU(N) and quarks belonging to arbitrary representations of SU(N) form a rich landscape of QCD-like theories, whose study can shed new light on the properties of confinement.

On the Meaning of Localization in Non‐Local Quantum Field Theory

open access: yesAnnalen der Physik, Volume 538, Issue 6, June 2026.
In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...

Single Top as Window on Heavy Quarks and Other New Physics

open access: yesAdvances in High Energy Physics, 2013
This paper discusses what the study of the electroweak production of single top quarks can tell us about additional quark generations, and how to distinguish the new quarks hypothesis from other kinds of new physics. We also suggest some new studies that

Why Quarks Are Unobservable

open access: yesPhilosophia Scientiæ, 2009
This essay deals with the question whether quarks—the basic components of matter and one of the youngest confirmed particles in high energy physics—can be observed directly or indirectly.

A Hybrid Semi‐Inverse Variational and Machine Learning Approach for the Schrödinger Equation

open access: yesAdvanced Physics Research, Volume 5, Issue 6, June 2026.
A hybrid semi‐inverse variational and machine‐learning framework is presented for solving the Schrödinger equation with complex quantum potentials. Physics‐based variational solutions generate high‐quality training data, enabling Random Forest and Neural Network models to deliver near‐perfect energy predictions.

The direct coupling of light quarks to heavy di-quarks

open access: yesPhysics Letters B, 2019
In the limit mQ>mQvrel>mQvrel2≫ΛQCD hadronic states with two heavy quarks Q should be describable by a version of HQET where the heavy quark is replaced by a di-quark degree of freedom.

Oxygen Supplementation Improves Oxygen Uptake Kinetics and Exercise Performance in PAH and CTEPH Patients

open access: yesComprehensive Physiology, Volume 16, Issue 3, June 2026.
In patients with pulmonary vascular diseases (PAH and CTEPH), supplemental oxygen (FiO2 0.3), compared to room air (FiO2 0.21) improved peak exercise capacity (peak V̇O2), peak sustainable exercise (V̇O2 at GET), and V̇O2 kinetics and the onset of exercise.

CLASSIFICATION OF PARTICLES AT ARBITRARY QUANTITY OF GENERATIONS. II. LEPTONS

open access: yesEast European Journal of Physics, 2017
The hypothesis on quark nature of the leptons is proposed. Leptons are compacted q3 -systems. It ensures the equality of modules for the electric charges of the proton and the electron. The classification of particles based on the U(Nf,g)×SU(3,c)×SU(4,fs)
