Quantum Tomography of Fermion Pairs in $e^{+} e^{-}$ Collisions: Longitudinal Beam Polarization Effects

Yu-Chen Guo, Tao Han, Matthew Low +1

We present a quantum tomography study of fermion pair production at future $e^{+} e^{-}$ colliders, emphasizing how longitudinal beam polarization controls the two-qubit spin density ma…

Muon collider probes of the gluonic quartic gauge couplings

Yu-Chen Guo, Peng-Cheng Lu, Tong Arthur Wu

We investigate the dimension-8 gluonic quartic gauge couplings (gQGCs) at future high-energy muon colliders through the process $I^¼^{+} I^¼^{-} \to g g I^^{3}$ . Using detailed event simul…
