El INCLUSIVE SPECTRA OF CHARGED HADRONS FROM ; I , AND iI ' DECAYS

The inclusive charged hadron momentum spectra from the $ and $' decays produced in e+ecoilisions at SPEAR are presented, The data were obtained with a small solid-angle, single-arm magnetic spectrometer with good particle identification abilities centered at 90 degrees with respect to the beams. The particle-separated invariant cross sections are compared with data from e+ecollisions at 6 = 4.8...

A SEARCH FOR UNCONVENTIONAL TAU DECAYS AND MEASUREMENT OF THE TAU PRODUCTION CROSS SECTION IN e+e- ANNIHILATIONS AT SPEAR*

ble present the results of an experimental study of two properties of the tau lepton performed with the MARK II detector in the SPEAR e+estorage ring at SLAC. The tau production cross section in e+eannihilation between 3.85 and 6.85 Gev in the center of mass has been measured using e-u events, and is consistent with the spin l/2, point cross section. The branching ratio product for the electron...

HADRON PRODUCTION IN e + e - ANNIHILATION FROM , / i = 5 . 0 TO 7 . 4 GeV

The total cross section for e+e-annihilation into hadrons has been measured * by the Crystal Ball collaboration at the SLAC storage ring SPEAR, for center-of-mass energies 4 from 5.0 to 7.4 GeV. The data show no evidence for new thresholds or resonant structure in this energy range. The average value of R, the radiatively corrected total hadronic cross section divided by the point p-pair cross ...

INTRODUCTION In the seven months since the discovery of the 3 particles we have been systematically studying their properties and decays at SPEAR. We have learned a great deal and most, but not all, of the pieces seem to be falling into place. I will review today the determination of the widths and quantum.numhers of these particles and the ongoing study of their decay modes. I will also +repor...

Hadron Therapy in Iran: Patient Indication Estimation and Challenges Ahead

Introduction: Radiotherapy with heavy charged particles such as protons and carbon ions (hadron therapy) has been recognized as an advanced technique for the treatment of various cancers. For some indications such as pediatric and radio-resistant tumors, it is considered the preferred method. However, despite its remarkable benefits, development of hadron therapy centers in the...
