The Large Hadron Collider (LHC) has been successfully delivering proton-proton collision data at the unprecedented center of mass energy of 13 TeV.
An upgrade is planned to increase the instantaneous luminosity delivered
by LHC in what is called HL-LHC, aiming to deliver a total of about 3000/fb of data to the ATLAS detector. To cope with the expected data-taking conditions ATLAS is planning...
The recent realization that highest energy p-p data can be simply explained in terms of a black disc with a constant `edge' is elucidated. The application to nuclei has significant implications for the understanding of cosmic ray showers. Another interesting point concerns understanding the coefficient of the Froissart bound in the limit of zero pion mass.
