Effect of uu diquark suppression in proton splitting in Monte Carlo event generators
نویسندگان
چکیده
Monte Carlo event generators assume that protons split into (uu)-diquarks and d-quarks with a probability of 1=3 in strong interactions. It is shown in this paper that using a value of 1=6 for the probability allows one to describe at a semi-quantitative level the NA49 Collaboration data for pþ p → pþ X reactions at 158 GeV=c. The Fritiof (FTF) model of Geant4 was used to simulate the reactions. The reduced weight of the (uu)-diquarks in protons is expected in the instanton model.

Introduction: Recently, an approach exploiting the proton therapy biological enhancement by using Boron atoms injected inside a tumor, has been proposed. Three alpha particles with an average energy around 4MeV are emitted from the point of reaction between a proton and boron. In addition, the 719 keV prompt gamma emitted by the proton Boron fusion reactions can be used for on-...
