“…A sample of about 1.4 million hadronic Z decays, selected among the data recorded by the DELPHI detector at LEP during 1994, was used to measure for the first time the momentum spectra of K+, K0, p, Λ and their antiparticles in gluon and quark jets. As observed for inclusive charged particles, the production spectra of identified particles were found to be softer in gluon jets than in quark jets, with a higher total multiplicity. © 1997 Published by Elsevier Science B.V.…”

Quark mass models and reinforcement learning by Lukas, A, Harvey, TR

“…As an example environment, we use the space of Froggatt-Nielsen type models for quark masses. Using a basic policy-based algorithm we show that neural networks can be successfully trained to construct Froggatt-Nielsen models which are consistent with the observed quark masses and mixing. …”

Perturbative and non-perturbative interactions between heavy quarks and quark-gluon plasma within a unified approach by Wen-Jing Xing, Guang-You Qin, Shanshan Cao

“…In this work, we extend the linear Boltzmann transport model by implementing a generalized Cornell-type potential that incorporates both short-range Yukawa interaction and long-range color confining interaction between heavy quarks and the QGP medium. Combining our new approach for heavy-quark-QGP interaction with a (3+1)-dimensional hydrodynamic model CLVisc for the QGP evolution and a hybrid fragmentation-coalescence model for heavy quark hadronization, we obtain a satisfactory description of heavy meson RAA and v2 from low to intermediate to high pT observed at both RHIC and the LHC. …”

CLASSIFICATION OF THE HADRONIC DECAYS OF THE Z0 INTO B-QUARK AND C-QUARK PAIRS USING A NEURAL NETWORK by Abreu, P, Adam, W, Adye, T, Agasi, E, Alekseev, G, Algeri, A, Allen, P, Almehed, S, Alvsvaag, S, Amaldi, U, Anassontzis, E, Andreazza, A, Antilogus, P, Apel, W, Apsimon, R, Asman, B, Augustin, J, Augustinus, A, Baillon, P, Bambade, P, Barao, F, Barate, R, Barbiellini, G, Bardin, D, Barker, G

“…A classifier based on a feed-forward neural network has been used for separating a sample of about 123 500 selected hadronic decays of the Z0, collected by DELPHI during 1991, into three classes according to the flavour of the original quark pair: uu+dd+ss (unresolved), cc and bb. The classification has been used to compute the partial widths of the Z0 into b and c quark pairs. …”

Global fit of modified quark couplings to EW gauge bosons and vector-like quarks in light of the Cabibbo angle anomaly by Andreas Crivellin, Matthew Kirk, Teppei Kitahara, Federico Mescia

“…These discrepancies, known as the Cabibbo Angle anomaly, can in principle be solved by modifications of W boson couplings to quarks. However, due to SU(2) L invariance, Z couplings to quarks are also modified and flavour changing neutral currents can occur. …”
