Since its approval in 2016, NA64 has pioneered Light Dark Matter (LDM) searches with electron [1],positron [2], muon [3], and hadron [4] beams. The experiment has successfully met its primary objec-tives, as outlined in the EPPS input (2018), and even exceed them producing results that demonstrateits ability to operate in a near-background-free environment. The Physics Beyond Collider (PBC)initiative at CERN recognizes NA64’s contributions as complementary and worthy of continued ex-ploration. Its key advantage over beam-dump approaches is that the signal rate scales as(coupling)*2rather than(coupling)*4, reducing the required beam particles for the same sensitivity.To fully exploit the NA64 physics potential, an upgrade during LS3 will enable NA64 to runin background-free mode at higher SPS beam rates. Planned upgrades include (a) improved detectorhermeticity with a new veto hadron calorimeter, (b) enhanced particle identification with a synchrotronradiation detector, and (c) increased beam rates via upgraded electronics.With the recently strengthened NA64 collaboration, stable operations and timely data analysisare planned for LHC Run 4. The expected∼10*1*3electrons,∼10*1*1positrons (40 and 60 GeV), and∼2×10*1*3muons on target will allow NA64 to explore new light dark matter regions, with the potentialfor discovery or conclusive exclusion of many well-motivated LDM models.
