چکیده
Recent theoretical investigations of high energy nucleon-nucleon collisions1) support the two-center model of multiple meson production as discussed by Ciok, et al.2 ) . To facilitate a prediction of the most probable distribution of shower particles as a function of laboratory energy, Farley's kinematical treatment of the "two-fireball" model is employed 3). A statistical determination of the multiplicity of pion (including neutrals) production per collision is assumed to be valid with possible corrections suggested through restrictions imposed by experi mental values of the inelasticity, Κπ . Acknowledgments The authors would like to take this opportunity to thank Professors Matthew Sands and Harold Ticho for making several interesting comments and for participating in many useful discussions.

Report CTSL-21 CALIFORNIA INSTITUTE OF TECHNOLOGY Synchrotron Laboratory Pasadena, California R.F. SYNCHRONIZATION DURING TRANSFER IN THE CASCADE SYNCHROTRON
If a low energy synchrotron is to be used as an injector for a 300 Bev machine, the problem may arise of synchronizing the two R.F. systems at transfer time in order that a bunch of protons in the injector may be transferred to a bucket in the main machine without loss of particles. A possible synchronization scheme is proposed and investigated here.
متن کاملThe chiral effective pion – nucleon Lagrangian of order p 4 # 1
We construct the minimal effective chiral pion–nucleon SU(2) Lagrangian at fourth order in the chiral expansion. The Lagrangian contains 114 in principle measurable and 4 contact terms needed for the renormalization. We develop both the relativistic as well as the heavy baryon formulation of the effective field theory. For the latter, we also work out explicitly all 1/m corrections at fourth or...
