素粒子物理学は,物質の根源を最も細かなレベルで解明することを目指す学問である。その素粒子物理学の概要を,できるだけ平易に3回の講座を通じて紹介する。第1回の本稿では,クォーク及びレプトンと名付けられている最も基本的な粒子を解説する。クォークは,陽子や中性子,湯川秀樹博士が予言した中間子等を形作っている素粒子であり,ニュートリノや電子,そして仁科芳雄博士の発見したミューオンはレプトンと呼ばれる。 

Introduction to Elementary Particles 2

素粒子物理学の概要を,3回にわたり平易に解説する。第2回の本稿では,電磁相互作用を媒介する光子などのゲージ粒子を説明する。ゲージ粒子の本質はゲージ対称性にあり,対称性の違いによりゲージ粒子が媒介する相互作用の特質が異なってくる。素粒子物理学で重要になる弱い相互作用及び強い相互作用を媒介するゲージ粒子を説明する。また重要な概念である「対称性の破れ」について説明し,ヒッグス粒子の意義を解説する。

Weyl spinors and the helicity formalism

In this work we give a review of the original formulation of the relativistic wave equation for particles with spin one-half. Traditionally \`a la Dirac, it's proposed that the ``square root'' of the

Associated Production of W + Charm in 13 TeV Proton-Proton Collisions Measured with CMS and Determination of the Strange Quark Content of the Proton

This thesis presents the measurement of of associated production of a W boson and a charm quark (W+ c) in proton-proton collisions at a center-of-mass energy of 13TeV. The data used in this analysis

Search for Higgs boson production in association with a top quark pair in two same-sign lepton final states with the ATLAS detector at LHC

The Large Hadron Collider (LHC) at CERN restarted in spring 2015 for three years (Run2) at an unexplored center-of-mass energy of 13 TeV; An ideal place to search for physics beyond the Standard

Physical Identifications for the Algebraic Quantities of Five-Dimensional Relativity

When four-dimensional general relativity is embedded in an unconstrained man-ner in a fifth dimension, the physical quantities of spacetime can be interpreted as geometrical properties related to the

Attractive Heaviside-Maxwellian (Vector) Gravity from Special Relativity and Quantum Field Theory

Adopting two independent approaches (a) Lorentz-invariance of physical laws and (b) local phase invariance of quantum field theory applied to the Dirac Lagrangian for massive electrically neutral

On the Nature of Cosmic-Ray Particles

Various authors1 have taken the view that cosmic-ray particles consist of two or more kinds of corpuscles. According to Compton and Bethe, and Auger1, the soft component near sea level is thus
