A Study of Hadronic Interactions in CBGEANTFLUKA vs GHEISHAA

چکیده

The results from a study on the behavior of the GEANT 3.21 Monte Carlo program are presented. The purpose was to study the diierent options available for hadronic interactions, and where possible to compare with data. and ? hadrons were studied at discrete momenta from 100 MeV/c to 1.0 GeV/c. The main conclusion is that the hadronic package currently employed in the CBGEANT Monte Carlo is wrong. It uses the wrong cross-sections and does not represent the data well. The choice between the correct version of GHEISHA and FLUKA is less clear, the pros and cons of which should be weighted by the user according to his/her application. Finally, there have been dramatic changes to the neutron transportation code between GEANT versions 3.14 and 3.21.

MULTIHADRON PRODUCTION FOR e e FOR FROM 50 TO 61 GeV, C. M. ENERGIES AND COMPARISON WITH MULTIHADRON PRODUCTION IN HADRONIC INTERACTIONS

Average values of< 1- T >where T is the thrust are presented for e: e: AMY data and are compared with their values in hadronic interactions. As far as possible, similar analysis techniques have been employed in the two different interactions. Similar variation with E is observed for this average in both data. The values of < PT> and < PL > relative to the thrust axis in e e are simila...

In the Hadronic interactions, the point which is less considered is the mass effect of interacting Hadrons on the energy distribution function of outgoing Hadrons. In this article we present a method to incorporate these mass effects which leads us to improve one of the basic formulas in QCD. In the end, we will show how these mass effects improve our previous results.

Disagreement and Degrees of Assertiveness in Service Encounters: Purchase vs Problem-Solving Interactions

This paper examined disagreement in two sets of data in the context of service encounters: problem-solving interactions (doctor-patient communication) and purchase-oriented encounters (pharmacies) from a cross-cultural perspective (Spanish-British English). We proposed assertiveness, a term that refers to both socio-psychological and linguistic features of communication, as a concept that may h...

The response of Geant4 hadronic models to the study of neutrons produced in proton irradiation to the light materials

Neutron is one of the products of the interaction of high energy protons with light nuclei. Using computational Monte Carlo codes, it is possible to calculate and predict the neutron spectrum, neutron flux, and doses by simulating the system. But the use of different hadronic models in this process can influence the results of these calculations. In this research, the response of the four hadro...

مطالعه دینامیکی حالتهای چند کوارکی

  Diquarks may play an important role in hadronic physics particularly near the phase transitions (chiral, deconfinement points). By using vector diquark ideas in the chiral limit diquark correlations in the relativistic region and imposing HF interactions between quarks in a vector diquark, we calculate the mass of Theta pentaquark state. Also by using the tunnelling method we simultaneously c...
