Phenomenological Studies of Electron-Proton Scattering at High Energies

我们调查了以下三个问题：1。我们将基本粒子反应的自动计算系统推广到超对称理论中。我们发现了一个一致的算法来生成这样的过程。在我们的研究中，我们发现了一个重要的点，即自动生成涉及马约拉纳费米子和费米子数违反相互作用的过程的算法。我们还根据新算法构建了系统，并通过计算各个过程对系统进行了测试。我们还将我们的方法扩展到电子-质子散射的深度非弹性过程。在这个扩展中，我们构建了一个系统来自动选择基本过程以固定最终状态。电子-质子系统的另一个点是由于强相互作用而产生的初始态辐射。风味单组分的多组分生产存在困难。为了将蒙特卡罗技术扩展到部分子簇世代，我们研究了一种利用动量分布演化的新算法。与利用粒子数分布演化的传统方法相比，该方法的计算结果简单准确。

We have investigated following three problems :1.We extended an automatic computation systen for reactions of elementary particles in to supersymmetric theories. We found that a consistent algorithm for generation of such processes. One of the important points which we found in our research is that an algorithm for the automatic ganeration of the processes involving Majorana fermions as well as the fermion number violating interactions. We also constructed the system accordirg to the new algorithm and tested the system by calculating various processes.2.We also extended our method to deep inelastic processes of the electron-proton scatterirg. In this extension, we constructed a system to select elementary processes automatically for fixed final states.3.Another point for the electron-proton system is the initial state radiations due to strong interactions. Difficulty arises from multi-parton production for the flavor singlet partons. In order to extend Monte Carlo technique for the parton shower generations, we investigated an new algorithm in which evolution of momentum distributions is used. We found that this new method gives simple and accurate results compared with conventional method in which the evolution of particle number distributions is used.
