Physics with the Pretzel LEP

  • D. Treille
Conference paper


A new option was recently proposed for LEP [1]: multibunch operation on the Z, providing a tenfold increase in luminosity. This is known as the pretzel*) scheme [2]. Physics-wise, no thorough study — such as was done for LEP 200 and for polarization on the Z — has yet been carried out. Therefore, these preliminary and personal remarks should be considered with reservation, since they rely more on guesses than on detailed studies.
