Effect of Hadron Dynamics on the Proton Lifetime
نویسندگان
چکیده
A detailed, quantitative re-examination of the effect of hadron dynamics on baryon decay, modeled in terms of Skyrme-field tunneling, indicates that any hadronic suppression should be quite mild. This appears to be another illustration of the ‘Cheshire-cat’ phenomenon, that variation of the apportionment between description of the nucleon as a bag of quarks and description as a Skyrme field configuration has little influence on many nucleon properties. Perhaps the largest remaining uncertainty in evaluating the decay rate has to do with the overlap between a specified quark-antiquark configuration and a final meson state.

Secondary Particles Produced by Hadron Therapy
Introduction Use of hadron therapy as an advanced radiotherapy technique is increasing. In this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. In this study, Monte Carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. Materials and Methods I...
متن کاملComparison of Different Model Predictions on RBE in the Proton Therapy Technique Using the GATE Code
Recently, proton therapy is used as one of the effective methods for treating various types of cancer in clinical treatment. An appropriate formalism to obtain relative biological effectiveness values for treatment planning studies is needed in this hadrontherapy technique. Hereby, the quantity of biological dose, instead of using the physical doses, is introduced to evaluate the biological eff...
متن کاملAn investigation of using hump in the Cherenkov photon lateral distribution for Gamma-Hadron separation
Simulation of gamma and hadron showers in the energy range 100GeV- 25TeV has been carried out. For a big ideal Cherenkov light array, characteristics of lateral distribution of Cherenkov photon density have been studied. Results from this ideal detector are compared with those simulated for a real TUNKA- like array to investigate experimental potential of using existence of a hump in lateral di...

Background: Hadron therapy for malignant tumor is becoming increasingly popular. There are many factors which effect on implementation of a proper treatment planning. The purpose of this work is to investigate the inhomogeneity effects as affecting factor on proton range, Full width at half maximum (FWHM) and 20% position of penumbra (P20) by MCNPX code. Materials and Methods: An inhomogeneous ...
متن کاملPhoton + Hadron Production in High Energy Deuteron (Proton)-Nucleus Collisions
We apply the Color Glass Condensate formalism to photon + hadron production cross section in high energy deuteron (proton)-gold collisions at RHIC. We investigate the dependence of the production cross section on the angle between the produced hadron and photon for various rapidities and transverse momenta. It is shown that the angular correlation between the produced hadron and photon is a sen...
