OSU ranks 31 according to ARWU-Physics-2015 and 25 according to US News/Physics. That sounds good enough, except for two facts which I want to be clarified. 1) According to gradschoolshopper.com the acceptance rate at OSU-Physics PhD in Fall 2015 was 35%, which seems quite high for a school of this rank. Doesn't that imply something negative about the quality of the enrolled students? 2) I'm afraid that this good enough rank is largely due to their so strong astronomy program, and therefore maybe their HEP-th/ex (which is what I essentially care about) is not necessarily strong? Of course I don't take the rankings too seriously or too strictly, but at least they may be a good first order approximation of quality. If all the above was too long to read, my question simply is: How strong is OSU HEP-Th/Exp compared to top tier schools? Can it be safely considered a good second tier department at HEP? I simply cannot answer this question based on counting citations of the faculty because that doesn't guarantee the quality of their publications, and I lack the ability to measure that quality at this stage. I also cannot gauge the strength and difficulty of their offered courses, because I don't think there's enough details on their website to do that.
