<p>The unit aims to introduce the basics of particle physics, namely the standard model of particle physics. All fundamental particles and the forces between them will be discussed, including a discussion of the hadron structure, decay rates and a short introduction to open questions of the standard model and beyond the standard model physics. Students will acquire a set of basic tools necessary in particle physics, in particular Feynman diagrams and relativistic kinematics. </p>
<p><i>On the successful completion of the course, students will be able to: </i></p><p>ILO 1</p><p>Understand the particles and forces of the standard model and perform basic kinematic calculations, and basic cross section and decay rate calculations. </p><p>ILO 2</p><p>Identify the basic interactions of the standard model and be able to draw Feynman diagrams for given processes. </p><p>ILO 3</p><p>Describe the symmetries and quantum numbers important in particle physics and apply these to particle physics processes. </p><p>ILO 4 </p><p>Understand the structure of hadrons and parton distribution functions required for hadron collider physics. </p><p>ILO 5</p><p>Identify the shortcomings of the standard model and possible solutions. </p>

<p>Two one hour, live in-person lectures per week where the core material with examples will be delivered. The recordings of these lectures will be on the course online page. The lectures are accompanied by summary notes. Example sheets will be provided in line with the scheduled 3rd year workshops. A Piazza discussion forum will also provided where students can ask questions with answers provided by other students and the unit lead. </p>
