Spin-spin entanglement at high energy
Michael Fucilla, Yoshitaka Hatta, Bo-Wen Xiao
Spin correlations offer a quantum-information perspective on the partonic final states produced in high-energy scattering. We discuss the spin-density matrix of a heavy quark-antiq…
Probing Saturation Effect in Heavy Meson Pair Correlation in Forward Collisions
Zhan Gao, Cyrille Marquet, Yu Shi +1
Forward two-particle angular correlations in collisions have long been recognized as a particularly sensitive observable for exploring gluon saturation effects. In the back-to…
Quantum entanglement in electron-nucleus collisions: Role of the linearly polarized gluon distribution
Michael Fucilla, Yoshitaka Hatta, Bo-Wen Xiao
We calculate the spin density matrix of a back-to-back quark-antiquark pair inclusively produced in electron-nucleus scattering, taking into account the gluon saturation effect and…
Polarization, Maximal Concurrence, and Pure States in High-Energy Collisions
Yu-Xuan Liu, Wei Qi, Luo-Ting He +1
We establish a quantitative relation between local spin polarization and quantum entanglement in two-qubit systems by mathematically proving a closed-form upper bound on the concur…
Unified Resummation of Soft Gluon Radiation in Heavy Meson Pair Photoproduction
Cyrille Marquet, Yu Shi, Bo-Wen Xiao
We develop a unified resummation framework for heavy-meson pair photoproduction that treats soft-gluon radiation in a massive scheme for and is consi…
Extracting Essential Non-perturbative Information in Jet Invariant Mass via the Bayesian Analysis
Zhan Gao, Yu Shi, Bo-Wen Xiao +1
In this paper, we present a new three-dimensional non-perturbative (NP) function to account for and parameterize the NP contributions in the jet invariant mass spectrum, in additio…
