Title: Energy dependence of $K / π$ fluctuations in relativistic heavy-ion collisions

Abstract

In this paper, we will discuss the energy dependence of particle ratio fluctuations in heavy-ion collisions. Additionally, we study how the inherent multiplicity dependence of ratio fluctuations is reflected in the excitation function of the dynamical fluctuations. Specifically, we will show that the observed excitation function of dynamical K/π fluctuations is consistent with the expected dependence on the number of accepted pions and kaons in both the STAR and the NA49 experiments.

Energy dependence of K/pi fluctuations in relativistic heavy-ion collisions

Journal Article Koch, Volker ; Schuster, Tim ; Department of Physics, University of Frankfurt, Frankfurt - Physical Review. C, Nuclear Physics

In this article we will discuss the energy dependence of particle ratio fluctuations in heavy-ion collisions. We study how the inherent multiplicity dependence of ratio fluctuations is reflected in the excitation function of the dynamical fluctuations. Specifically, we will show that the observed excitation function of dynamical K/pi fluctuations is consistent with the expected dependence on the number of accepted pions and kaons in both the STAR and the NA49 experiments.

$K \to (π π)_{I = 2}$ Decay Amplitude from Lattice QCD

Journal Article Blum, T. ; Boyle, P. A. ; Christ, N. H. ; ... - Physical Review Letters

We report on the first realistic ab initio calculation of a hadronic weak decay, that of the amplitude A₂ for a kaon to decay into two π mesons with isospin 2. We find ReA₂=(1.436±0.063_stat±0.258_syst)10^-8 GeV in good agreement with the experimental result and for the hitherto unknown imaginary part we find ImA₂=-(6.83±0.51_stat±1.30_syst)10^-13 GeV. Moreover combining our result for ImA₂ with experimental values of ReA₂, ReA0, and ϵ'/ϵ, we obtain the following value for the unknown ratio ImA₀/ReA₀ within the standard model: ImA₀/ReA₀=-1.63(19)_stat(20)_syst×10^-4. One consequence of these results is that the contribution from ImA₂ to the direct CP violation parameter ϵ'more »« less

Here, we report measurements of sin 2β and cos 2β from a time-dependent Dalitz plot analysis of B⁰ → D(*)h⁰ with D → K⁰_Sπ⁺π^– decays, where the light unflavored and neutral hadron h⁰ is a π⁰, η, or ω meson. The analysis is performed with a combination of the final data sets of the BABAR and Belle experiments containing 471 x 10⁶ and 772 x 10⁶ BB pairs collected at the Υ(4S) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively.
