Disoriented isospin condensates may be the source of anomalous kaon correlations measured in Pb-Pb collisions at s N N = 2.76 TeV

The magnitude of fluctuations between charged and neutral kaons measured by the ALICE Collaboration in heavy-ion collisions at the LHC exceeds conventional explanation. Here it is shown that if the scalar condensate, which is typically associated with chiral symmetry, is accompanied by an isospin = 1 field, then the combination can produce large fluctuations where 〈 u ¯ u 〉 ≠ 〈 d ¯ d 〉 . Hadronizing strange and antistrange quarks might then strongly fluctuate between charged ( u s ¯ or s u ¯ ) and neutral ( d s ¯ or s d ¯ ) kaons. Published by the American Physical Society 2024
