Abstract

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 (us¯ or su¯) and neutral (ds¯ or sd¯) kaons.
