Module summary
The module is a natural extension of the Y2 Particle and Nuclear Physics module, but goes into a more detailed discussion of underlying physics phenomena, with a much more advanced usage of quantum mechanics.
In the Nuclear Physics part,. the properties of ground and excited states of nuclei, especially of odd-mass and odd-odd are covered within the concepts of spherical and deformed shell models. Particular importance is paid to the application of Schrodinger Equation for a central potential and angular momenta coupling phenomena. The alpha/beta/gamma/fission decays and their probabilities are extensively discussed based on quantum-mechanical basis. Some examples of modern experimental techniques and measurements in real research environment (e.g. at CERN) are given. The basics of fission and fusion research and applications will also be covered.
The course will give an overview of the physics, methods and equipment employed in modern particle physics. The basic interaction processes of various particles with each other are outlined, including the interaction of strongly, electro-magnetically, weakly and gravitationally interacting particles. All Standard Model (SM) particles and interactions will be reviewed, including possible extension of SM and physics beyond the SM.

Module aims
In terms of nuclear physics, this module will focus on advanced topics of nuclear structure and decays, and begin to examine how these topics are addressed in contemporary nuclear physics research. We will examine the key nuclear models that underpin nuclear structure, in particular spherical and deformed shell models, and show their links to both “single-particle” and “collective” modes of excitation. The module then continues to develop understanding of the quantum mechanical mechanisms underlying nuclear decays and, hence, to examine what nuclear structure information can be extracted from such measurements. The physics of nuclear fission and fusion will be discussed as well as the principles of operation of fission and fusion reactors. In all of the above, published data will be used regularly to illustrate and test the ideas presented.
In terms of particle physics, this course will outline the latest developments and methods used in detector construction and data analysis. The effects of particle oscillations will be reviewed based on Kaon and neutrino oscillations experiments. Large part of the course will be devoted to the use of Feynman graphs reaction dynamics with strong electromagnetic weak and even gravitational interactions. Some practical skills based on symmetries and in particular isospin gymnastics will be discussed in detail in lectures and seminars. The module will review modern and planned PP experiments (LHC, EIC, JLab, BELLE2, PANDA, supercollider, JPARC), describing experiments with primary and secondary beams (collider and fixed target mode). Several problematic areas, like Dark matter particles problem, incorporation of gravity into the SM will be also uncovered.

Module feedback
'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme. We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments.
A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback. This can be found at:
https://www.york.ac.uk/students/studying/assessment-and-examination/guide-to-assessment/
The School of Physics, Engineering & Technology aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. Students are provided with their examination results within 25 working days of the end of any given examination period. The School will also endeavour to return all coursework feedback within 25 working days of the submission deadline. The School would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The School will endeavour to keep such delays to a minimum. Please note that any marks released are subject to ratification by the Board of Examiners and Senate. Meetings at the start/end of each semester provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.
Our policy on how you receive feedback for formative and summative purposes is contained in our Physics at York Taught Student Handbook.
