{{Short description|One of nine detector experiments at CERN}}

{{LHC}}
The '''TOTEM experiment''' ('''TOTal Elastic and diffractive cross section Measurement''') is one of the nine [[Particle detector|detector]] experiments at [[CERN]]'s [[Large Hadron Collider]]. The other eight are: [[ATLAS experiment|ATLAS]], [[ALICE experiment|ALICE]], [[Compact Muon Solenoid|CMS]], [[LHCb experiment|LHCb]], [[LHCf experiment|LHCf]], [[MoEDAL experiment|MoEDAL]], [[FASER experiment|FASER]] and [[Scattering and Neutrino Detector|SND@LHC]]. It shares an [[interaction point]] with CMS. The detector aims at measurement of total [[cross section (physics)|cross section]], [[elastic scattering]], and [[diffraction]] processes. The primary instrument of the detector is referred to as a [[Roman pot]]. In December 2020, the D0 and TOTEM Collaborations made public the [[odderon]] discovery based on a purely data driven approach in a CERN and Fermilab approved preprint that was later published in Physical Review Letters.<ref name="Abazov Abbott Acharya et al 2021">{{cite journal |last1=Abazov |first1=V.

When combined with TOTEM experimental data at 13 TeV at small scattering angles providing an odderon significance of 3.4 - 4.6 σ, the combination resulted in an odderon significance of at least 5.2 σ.<ref>{{Cite web |date=2021-03-09 |title=Odderon discovered|url=https://cerncourier.com/a/odderon-discovered/ |access-date=2022-02-11 |website=CERN Courier |language=en-GB}}</ref>
