Subject: Prospective PhD student: Grassmannian Dear Professor Cachazo, My name is [your name], and I am a [your current degree or role] at [your institution]. I am applying for a PhD position starting in [term and year]. I read your paper "Singularity structure of maximally supersymmetric scattering amplitudes." (2014), and it connects closely to my own work on [your research topic]. [One or two sentences on what you did and what you learned.] I also saw your NSERC-funded project "Scattering Amplitudes: Applications and Hidden Mathematical Structures" (2023), and I would be glad to contribute to work in that direction. Are you accepting new PhD students for [term and year]? I have attached my CV and transcripts, and I would be glad to talk at a time that suits you. Thank you for your time. Kind regards, [your name]
