Hadron interactions and hadron structure

چکیده
It was rst pointed out by Drell & Yan (1970) that parton model ideas developed for deep-inelastic scattering could be extended to certain processes in hadron{hadron collisions. The paradigm process, proposed by Drell & Yan, was the production of a massive lepton pair by quark{antiquark annihilation: the Drell{Yan process (illustrated in gure 1). For the production of a lepton pair of invariant mass M , the hadronic cross-section d 1⁄4 = dM 2 was to be obtained by weighting the subprocess cross-section d^ 1⁄4 = dM 2 for q·q! m + m ¡

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 کاملHadron 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...
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...
متن کاملComparison of the Light Charged Particles on Scatter Radiation Dose in Thyroid Hadron Therapy
Bachground: Hadron therapy is a novel technique of cancer radiation therapy which employs charged particles beams, 1H and light ions in particular. Due to their physical and radiobiological properties, they allow one to obtain a more conformal treatment, sparing better the healthy tissues located in proximity of the tumor and allowing a higher control of the disease. Â Objective: As it is well ...
متن کاملPreliminary Characterization Tests of Detectors of on-Line Monitor Systems of the Italian National Center of Oncological Hadron-Therapy (CNAO)
Introduction Hadron-therapy is an effective technique used to treat tumors that are located between or nearby vital organs. The Italian National Center of Oncological Hadron-therapy (CNAO) has been realized as the first facility in Italy to treat very difficult tumors with protons and Carbon ions. The on-line monitor system for CNAO has been developed by the Department of Physics of the Univers...

Energetic secondary particles in gamma and hadron initiated showers can generate Cherenkov photons. Using CORSIKA code and simulation data, different characteristics of lateral distribution of Cherenkov photon density are studied. In particular, physical origin of these differences and also dependence of this distribution on primary energy and altitude of observation level are discussed. It is ...
