Abstract

Precision predictions of soft and hard diffraction, elastic, and total protonproton cross sections, based on a Regge-theory inspired tensor-Pomeron implementation of the RENORM model, are compared to TOTEM, ATLAS, and CMS results at the LHC.

Highlights

In DIS-2015 (Spring 2015) we summarized [1] the pre-LHC predictions of the total, elastic and totalinelastic, as well as the single diffractive (SD) and double diffractive (DD) components of the protonproton cross section at high energies, based on the RENORM / MBR model [2]
The predictions were compared with measurements by ATLAS at s = 7 TeV and by TOTEM at s = 7 and 8 TeV at Moriond QCD in March 2016 [6] and found to be in good agreement
This is an update of [6] that inclu√des verbatim certain sections and describes new measurements of the total inelastic cross section at s = 13 TeV by ATLAS and CMS at DIS-2016 (April 2016)

Summary

Introduction

In DIS-2015 (Spring 2015) we summarized [1] the pre-LHC predictions of the total, elastic and totalinelastic, as well as the single diffractive (SD) and double diffractive (DD) components of the protonproton cross section at high energies, based on the RENORM / MBR model [2]. In Summer 2015 we updated the value of s0 to a more precise one based on a tensor glueball interpretation of the Axial Field Spectrometer (AFS) exclusive charged di-pion data [3,4,5] This change in RENORM / NBR decreases the uncertainties in the predictions of the total, elastic, and total-inelastic cross sections to less than 2% from Tevatron to LHC energies, with little√or no effect on the mean values√. The predictions were compared with measurements by ATLAS at s = 7 TeV and by TOTEM at s = 7 and 8 TeV at Moriond QCD in March 2016 [6] and found to be in good agreement This is an update of [6] that inclu√des verbatim certain sections and describes new measurements of the total inelastic cross section at s = 13 TeV by ATLAS and CMS at DIS-2016 (April 2016). We discuss these findings in an attempt to understand the origin of the observed discrepancies
