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

Annalen 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 ...

Model-independent constraints on the CKM matrix elements |V tb |, |V ts | and |V td |

Journal of High Energy Physics, 2019
Single top quark production cross sections at hadron colliders are traditionally used to extract the modulus of the V tb element of the Cabibbo-Kobayashi-Maskawa matrix under the following assumption: |V tb | ≫ |V td |, |V ts |.

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

Advanced 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.

Quantum tops at circular lepton colliders

Journal of High Energy Physics
We study the quantum properties of top quark pairs in lepton colliders with unpolarised beams, including spin correlations, entanglement, and violation of Bell inequalities.

The Top Quark

, 2015
On the twentieth anniversary of the observation of the top quark, we trace our understanding of this heaviest of all known particles from the prediction of its existence, through the searches and discovery, to the current knowledge of its production mechanisms and properties.

Monte Carlo Simulations of Heavy Particles for the Large Hadron Collider [PDF]

, 2013
As the Large Hadron Collider has switched on at CERN in Geneva, accurate predictions for complex hadronic processes are essential for the validation of theory and therefore the success of the machine.

Invariant-mass threshold resummation for the production of four top quarks at the LHC

Journal of High Energy Physics
Using invariant-mass threshold resummation, we compute the invariant-mass distribution and the total cross section for t t ¯ t t ¯ $$ t\overline{t}t\overline{t} $$ production at the LHC with centre-of-mass energy of 13.6 TeV at NLL′ accuracy.
