The TOTEM experiment (TOTal Elastic and diffractive cross section Measurement) is one of the eight detector experiments at CERN's Large Hadron Collider. The other seven are: ATLAS, ALICE, CMS, LHCb, LHCf, MoEDAL and FASER. It shares an interaction point with CMS. The detector aims at measurement of total cross section, elastic scattering, and diffraction processes. The primary instrument of the detector is referred to as a Roman pot. In 2021, the TOTEM collaboration published evidence for an interaction mediated by a odderon with a total significance of 6.26σ, but did not observe the particle or measure its mass.[1]
