We detect the peak of baryon acoustic oscillations (BAO) in the two-pointcorrelation function of a spectroscopic sample of $25226$ clusters selectedfrom the Sloan Digital Sky Survey. Galaxy clusters, as tracers of massive darkmatter haloes, are highly biased structures. The linear bias $b$ of the sampleconsidered in this work, that we estimate from the projected correlationfunction, is $b \sigma_8 = 1.72 \pm 0.03$. Thanks to the high signal in thecluster correlation function and to the accurate spectroscopic redshiftmeasurements, we can clearly detect the BAO peak and determine its position,$s_p$, with high accuracy, despite the relative paucity of the sample. Ourmeasurement, $s_p = 104 \pm 7 \, \mathrm{Mpc} \, h^{-1}$, is in good agreementwith previous estimates from large galaxy surveys, and has a similaruncertainty. The BAO measurement presented in this work thus provides a newstrong confirmation of the concordance cosmological model and demonstrates thepower and promise of galaxy clusters as key probes for cosmologicalapplications based on large scale structures.
