DESCRIPTION:Two-photon collisions constitute a prominent process in electr
 on-positron colliders\, producing final states with positive charge parity
  such as $\\pi^0$ and $\\chi_c(3915)$. These collisions play a critical ro
 le in discovering exotic hadronic states. While characterized by a small c
 ross section\, the increasing luminosity of modern colliders enables novel
  approaches to explore physics beyond the Standard Model – including glu
 eball searches\, charmonium-like state studies\, and future Higgs boson pr
 oduction at facilities like CEPC and FCC-ee.  \n\nThe Belle II experiment
 \, operating at a center-of-mass energy of $\\sqrt{s} \\approx 10.6$ GeV\,
  has achieved sustained data-taking with instantaneous luminosity exceedin
 g $5 \\times 10^{34}$ cm$^{-2}$s$^{-1}$\, marking a transformative era for
  two-photon physics. However\, the electron-positron pairs ($e^+e^-$) in t
 wo-photon final states frequently escape detection in the Belle II apparat
 us\, resulting in low reconstruction efficiency and elevated background le
 vels.  \n\nTo address these limitations\, this workshop will:  \n1. Exam
 ine two-photon collision physics in electron-positron colliders  \n2. Dis
 cuss innovative detector technologies for measuring escaping $e^+e^-$ pair
 s  \n3. Explore designs for complementary external detection systems\n\nT
 he workshop will be at the Yan Garden (燕园)\, Handan Campus\, Fudan Uni
 versity\, Shanghai.\n\n\n\nContact persons: Xiaolong Wang (xiaolong@fudan.
