We investigate a possibility of the odderon exchange detection at LHC with $K_s^0$ re-
generation measurement using (∼1 TeV) neutral $𝐾_𝐿^0$ mesons, originating from 𝑝 + 𝑝 (13.6 TeV)
collisions at the ATLAS Interaction Point (IP). The regenerator material considered is Carbon, and
metallic Pb or Cu, placed at distance ≥140m from the IP, behind (or in) TAN absorber. LHCf-type
of calorimeter is assumed to be capable of detecting the $K_s^0$ energy and “decay vertex” position
from $K_s^0$ meson decay to 𝜋 0 𝜋 0 → 2𝛾 + 2𝛾 pairs at distance 𝐿 < 150 m from the regenerator. We
recalculate the regeneration parameters from the published paper [1], which suggested the odderon
detection using 2 TeV $K_s^0$ regeneration in liquid hydrogen (LH 2 ). Our estimates for thick Pb, C
and Cu regenerators include the $𝐾^0$ absorption.
