Missing Energy Signatures of Inelastic Magnetic Dipole DM at NA64e / S.N.Gninenko, N.V.Krasnikov, I.V.Voronchikhin, D.V.Kirpichnikov. – Text : electronic // Physical Review D. – 2026. – Vol. 113, No. 11. – P. 115055. – URL: https://doi.org/10.1103/w86p-8mj9. – Bibliogr.: 93.
Some extensions of the Standard Model consider inelastic dark matter (iDM) as an attractive candidate for sub-GeV DM of thermal origin that could be detected at modern accelerators. In the present paper, we calculate the production rate of iDM pairs 𝜒&sub(1)𝜒&sub(0)^- interacting with the ordinary photon via dipole magnetic moment in the reaction of high-energy electron scattering on nuclei, 𝑒*-𝑁 → 𝑒*-𝑁𝜒&sub(1)𝜒^-&sub(0), in the NA64e experiment at the CERN Super Proton Synchrotron (SPS). We derive the projected sensitivity of NA64e to such particles assuming ≃ 10*1*3 100 GeV electrons on target. We also show, that incorporating heavy vector meson decays, 𝛾*𝑁 →𝑁𝑉( →𝜒&sub(1)𝜒^-&sub(0)), alongside bremsstrahlunglike emission of inelastic dark matter pairs, 𝑒*-𝑁 →𝑒*-𝑁𝛾* ( →𝜒&sub(1)𝜒^-&sub(0)), will allow NA64e to probe previously unexplored regions of the iDM parameter space, in particular for modest mass splittings, Δ ≃5 ×10*-*2, and relatively light masses, 𝑚&sub(𝜒0) ≲ 100 MeV.
