چکیده
For the first time, production of a massive dark photon (DP) in $\gamma e^-$ scattering at future lepton colliders ILC, CLIC, and CEPC is examined. The invisible decay mode DP addressed. We have studied both unpolarized collision Compton backscattered photons with polarized electron. missing energy distributions are shown. considered wide range 10 GeV -- 1000 mass $m_{A'}$. excluded regions 95\% C.L. plane $(\varepsilon, m_{A'})$, where $\varepsilon$ kinetic mixing parameter, obtained.

Search for Invisible Decays of a Dark Photon Produced in e^{+}e^{-} Collisions at BaBar.
We search for single-photon events in 53 fb^{-1} of e^{+}e^{-} collision data collected with the BABAR detector at the PEP-II B-Factory. We look for events with a single high-energy photon and a large missing momentum and energy, consistent with production of a spin-1 particle A^{'} through the process e^{+}e^{-}→γA^{'}; A^{'}→invisible. Such particles, referred to as "dark photons," are motiv...
متن کاملProbing Lepton Flavor Violation at Future Colliders.
Supersymmetric theories with significant lepton flavor violation have ẽ and μ̃ nearly degenerate. In this case, pair production of ẽ+ẽ− and μ̃+μ̃− at LEPII and at the Next Linear Collider leads to the phenomenon of slepton oscillations, which is analogous to neutrino oscillations. The reach in ∆m2 and sin 2θ gives a probe of lepton flavor violation which is significantly more powerful than the cur...
متن کاملLepton Flavor Violation at Future Colliders
Motivated by the interest in lepton number violating processes, we study the connection between the rate of Z → μe decay and those of the low-energy processes μ → 3e, and μ → e conversion in nuclear field. We show that if the vector or axial Z form factors are dominant, Br(Z → μe) is not observable, while if the Z dipole form factors are dominant, the relatively weak indirect bound Br(Z → μe) <...
متن کاملParity Violating Asymmetries at Future Lepton Colliders
The International Linear Collider (ILC) will have tremendous discovery potential. Combining high energy and high luminosity capabilities, it will thoroughly explore e+e− collisions from √ s ≈ 500 GeV to 1.5 TeV. In addition, the possibility exists to run at lower energies, such as the Z pole ∼ 91 GeV, while retaining relatively high luminosity. There, one could carry out very precise measuremen...
متن کاملStrong Ww Scattering at Photon Linear Colliders ∗
We investigate the possibility of observing strong interactions of longitudinally polarized weak vector bosons in the process γγ → ZZ at a photon linear collider. We make use of polarization of the photon beams and cuts on the decay products of the Z bosons to enhance the signal relative to the background of transversely polarized ZZ pairs. We find that the background overwhelms the signal unle...
