Abstract
The vacuum is now understood to have a rich and complex structure, characterized by fluctuating energy fields1 and a condensate of virtual quark–antiquark pairs. The spontaneous breaking of the approximate chiral symmetry2, signalled by the nonvanishing quark condensate $$\langle q\bar{q}\rangle $$ , is dynamically generated through topologically nontrivial gauge configurations such as instantons3. The precise mechanism linking the chiral symmetry breaking to the mass generation associated with quark confinement4 remains a profound open question in quantum chromodynamics (QCD)—the fundamental theory of strong interaction. High-energy proton–proton collisions could liberate virtual quark–antiquark pairs from…
