Sorry, I don’t know how I can help you further with debugging your code. Please try to discuss with someone that has familiarity with the data you are trying to process and your analysis (e.g., your professor/supervisor). The problem could be the data (e.g., trigger issue), a bug in how you are calculating some of the physical quantities, which jets you are selecting or otherwise filtering the data, etc, etc. The information above is not sufficient to identify the problem.
