Abstract We present analytic results for three-loop fermionic corrections to the heavy-light form factors in perturbative quantum chromodynamics. Specifically, we present all light quark contributions and contributions from two heavy quark loops. We

Abstract Reaching a high precision of the top quark mass is an important task of the Large Hadron Collider. We perform a feasibility study of measuring the top quark mass through the three-point energy correlator. The expected sensitivity of the top

Abstract We present the analytic total cross section of top quark pair production in electron-positron annihilation at next-to-next-to-leading order (NNLO) in Quantum Chromodynamics (QCD). By utilizing the optical theorem, the NNLO corrections are re

Abstract We study the quantum properties of top quark pairs in lepton colliders with unpolarised beams, including spin correlations, entanglement, and violation of Bell inequalities. We present analytical results in the SM and in the SMEFT and discus

Abstract Quantum entanglement is a fundamental property of quantum mechanics. Recently, studies have explored entanglement in the t t ¯ $$ t\overline{t} $$ system at the Large Hadron Collider (LHC) when both the top quark and anti-top quark decay le

Abstract Jet tagging is a classification problem in high-energy physics experiments that aims to identify the collimated sprays of subatomic particles, jets, from particle collisions and ‘tag’ them to their emitter particle. Advances in jet taggi

Abstract Recent advancements in deep learning models have significantly enhanced jet classification performance by analyzing low-level features (LLFs). However, this approach often leads to less interpretable models, emphasizing the need to understan

Abstract We study the effects of four-heavy-quark operators in the production of top quarks in the framework of the Standard Model Effective Field Theory (SMEFT) at the LHC. In particular, we compute for the first time the total contribution of the f

Abstract We compute the two-loop master integrals for leading-color QCD scattering amplitudes including a closed light-quark loop in t t ¯ H $$ t\overline{t}H $$ production at hadron colliders. Exploiting numerical evaluations in modular arithmetic,

Abstract The production of a Higgs boson in association with a top-antitop quark pair t t ¯ H $$ \left(t\overline{t}H\right) $$ holds significant importance in directly probing the top-quark Yukawa coupling, which is related to various fundamental q
