Description
The dataset contains columns with detailed information from the 2011 TOTEM measurement conducted with the Roman Pot detectors. Data is provided in an NTuple format (.root file). Due to the close proximity of the detectors to the beam center (approximately 5 sigma beam) in a specific run with β* = 90 m, it covers |t|-values down to 5·10^{-3} GeV². The descriptions of the columns are provided below. The dataset is designed to facilitate easy access and analysis of the proton-proton scattering due to precalculated kinematic variables.
