Measuring intact protons at the LHC: From the odderon discovery to the search for axion-like particles
by
FYS2
In the first part of the talk, we will describe the odderon discovery by the TOTEM and D0 experiments. The analysis compares the p-pbar elastic cross section as measured by the D0 Collaboration at Fermilab at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at CERN at 2.76, 7, 8, and 13 TeV. The two data sets disagree at the 3.4 sigma level and thus provide evidence for the odderon. Combining these results with previous TOTEM results leads to a combined significance larger than 5 sigma.
In a second part of the talk, we will describe the search for axion-like particles with intact protons in the final state, leading to sensitivities to beyond standard model physics that improve by 2 to 3 orders of magnitude on the coupling compared to LHC standard methods.
We will finish by describing briefly the ultra fast silicon detectors for timing measurements as well as for medical and cosmic ray physics applications with KU medical and NASA.
