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 correlations in collisions have long been recognized as a particularly sensitive observable for exploring gluon saturation effects. In the back-to-back re…
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…
Lighting up the Photon Wigner Distribution via Dilepton Productions
Yu Shi, Lin Chen, Shu-Yi Wei +1
We present a systematic investigation of lepton pair production through photon-photon fusion processes in heavy-ion collisions. It is demonstrated that the dilepton production at a…
