Particle Physics
Goals of the lecture
The lecture course will cover the elementary particles of the Standard Model (SM) and their fundamental interactions, and will provide an introduction to expermental apparatus that made their discovery possible over the last decades. The present status of the SM of Elementary Particles, its experimental underpinnings, and its shortcomings will be discussed. An outlook to possible extensions of the SM will be given.
This lecture course is naturally a first step for a specialisation towards Particle Physics.

The lecture will give 8 credit points.
Tutorials
The tutorials are an integral part of the lecture, and all take place on Friday. The problem sheets are provided through this website, typically on Wednesdays. On Fridays of the same week, the students have the opportunity to discuss anything that may be unclear in the problem sheet formulation in the tutorials. The problem sheets solutions are then handed in on Fridays of the respective following week, graded, and the solutions are presented and discussed (by the students) on Fridays of the week after.
To successfully accomplish the tutorials, 60% of the points are needed. We encourage the students to work together in small groups of 3 (ideally) or 2 people. One solution per group is sufficient.
Exam
The exam will take place on Monday 11th February at 13h45 - 16h00 in INF 308 / HS 1 (HS 1 = big lecture hall in INF 308). Only the students who successfully accomplished the tutorials are admitted to the exam. Bring along your student ID with a picture, and a non-programmable pocket calculator without a WiFi/LTE function.
The exam review ("Klausureinsicht") will take place on Friday 15th February at 13h00-15h00 in INF 227 / HS 2.
The second retry exam (likely written) will take place 8h45 - 11h00 in Philos.-weg 12 / nHS on 12 April. We remind the students that this is a retry exam -- you are strongly encouraged to aim for passing the primary exam in February. In other words, the retry exam is considered a backup option in case of not passing the primary one.
