A Search for New Particles Produced by High Energy Photons*
نویسندگان
چکیده
A search for new particle s which might be produced by photons of energy up to 18 GeV is described. No new particles were found. Calculations of the Beth&-Heitler process are described which make it possible to state that this exper.iment would have detected non-strongly interacting particles whose mass and lifetime lay in a definite range, did they exist.

Evaluation of the dose and flux of secondary particles in the lung tissue in breast proton therapy using the Monte Carlo simulation code
Unlike proton therapy, conventional radiation therapy directs X-rays not only at the tumor but also unavoidably at nearby healthy tissue. Protons deliver radiation to tumor tissue while the healthy structures will be spared during proton therapy. When protons travel through matter, secondary particles like neutrons and photons are produced. It is believed that the secondary dose can lead to sec...

The LHC will soon start operating in an unexplored energy regime at √ s ∼ 14 TeV, about seven times higher than that achieved at the Tevatron. At that center-ofmass energy, a large number of new particles could be produced even in a data sample of modest integrated luminosity. The challenge is to distinguish events with new particles from those, many orders of magnitude more copious, attributed...

Despite major progress in radiotherapy, exponential attenuation of initial photons due to the nature of their interaction with matter has remained as the most important challenge. Photons have no well-defined range and their doses are reduced exponentially. Therefore, tissues located before and after the tumors receive a significant dose. Today, new techniques based on proton and carbon charged...

A search for ultra-high energy photons with energies above 1 EeV is performed using nine years of data collected by the Pierre Auger Observatory in hybrid operation mode. An unprecedented separation power between photon and hadron primaries is achieved by combining measurements of the longitudinal air-shower development with the particle content at ground measured by the fluorescence and surfac...
