| Summary: | The first measurements of isospin fluctuations in the kaon sector is presented in Pb-Pb collisions at <inline-formula> <math display="inline"> <semantics> <msqrt> <msub> <mi>s</mi> <mrow> <mi>N</mi> <mi>N</mi> </mrow> </msub> </msqrt> </semantics> </math> </inline-formula> = 2.76 TeV. A robust statistical observable was used to extract the isospin fluctuations of neutral and charged kaons as a function of collision centrality. The results show a significant variation in the behaviour of <inline-formula> <math display="inline"> <semantics> <msub> <mi>ν</mi> <mrow> <mi>d</mi> <mi>y</mi> <mi>n</mi> </mrow> </msub> </semantics> </math> </inline-formula> in data when compared to Monte-Carlo models such as HIJING and AMPT. The deviation from 1/n scaling in data indicates possible isospin fluctuation in the kaon sector in heavy ion collisions. |
