For those pursuing a master's degree in High Energy Physics in Europe, several universities are recommended, including EPFL, ETH Zurich, Imperial College London, and the University of Cambridge. It's crucial to choose a program based on specific subfields of interest, as the field is vast and diverse. Prospective students should conduct thorough research by reviewing relevant academic papers, which can help identify institutions and faculty members. Engaging with potential supervisors before applying is advised, along with inquiring about available scholarships and admission requirements. While arXiv is a useful resource for finding papers, caution is advised due to the volume of submissions and the lack of peer review, making it beneficial to focus on review articles or resources prepared for educational purposes.
