(Color online) Measured dynamical $K/\pi$ fluctuations in terms of $\nu_{dyn,K\pi}$ for 62.4 and 200 GeV Au+Au compared with $\sigma^{2}_{dyn}$ from central Pb+Pb collisions at 6.3, 7.6, 8.8, 12.3, and 17.3 GeV from NA49 [7]. Statistical errors are shown for the STAR data. Statistical and systematic errors are shown for the NA49 results. The solid line corresponds to a fit to the STAR data of the form $c + d/(dN/d\eta)$.

(Color online) The dN/dη scaled dynamical $K/\pi$ fluctuations for summed charges (stars), same signs (circles), and opposite signs (squares) as a function of $dN/d\eta$. The errors shown are statistical. The open and filled symbols refer to Au+Au collisions at 62.4 GeV and 200 GeV respectively. The dash-dot, dotted, and dashed lines represents HIJING calculations for summed charges, same signs, and opposite signs respectively.

The Z boson decays to $e^{+}e^{-}, \mu^{+}\mu^{-} \;\mathrm{or}\; \tau^{+}\tau^{-}$. All branching ratios in the Higgs boson decay chain are set to 100%. The product of acceptance times efficiency is defined by the fraction of simulated events that pass all the selection criteria of this analysis. The acceptance is defined by the fraction of simulated events that pass all the selection criteria as applied to Monte Carlo truth-level quantities. The efficiency is then defined as the acceptance times efficiency, divided by the acceptance.

Application of the modified ABCD method to the final high-E_T selections. The a priori estimate refers to the "pre-unblinding" case, where the data in region A are ignored by removing the Poisson constraint in that region and the signal strength is fixed to zero. This matches the simple N^bkg_A=(N^bkg_B· N^bkg_C)/N^bkg_D relation. The a posteriori estimate refers to the "post-unblinding" case, including the observed data in region A in the background-only global fit, obtained by fixing the signal strength to 0 (background-only fit) or allowing it to float (signal-plus-background fit). The table also shows one set of representative signal yields in each selection for the signal-plus-background fit. Only statistical uncertainties are included in the quoted error of the background, while the uncertainties in the signal include those from both statistical and experimental sources.

Efficiency for an event to enter Region A of the high-E_T selection, as a function of the two LLP kinematics, decay type and decay position. LLP p_T is binned in the ranges of [0, 50 , 100, 200 , 400, 1600] GeV (5 bins), the LLP decay position is binned in decay position in L_xy in [0, 1.5, 2, 2.5, 3, 3.5, 3.9, ∞] m for LLPs with |η| < 1.5 and L_z in [0, 3.6, 4.2, 4.8, 5.5, 6, ∞ ] m for LLPs with |η|geq1.5, 13 bins in all. Finally, four decay types are considered: LLPs decaying to pairs of c, b, t, or τ in bins 0, 1, 2, 3 respectively. The efficiency is presented as a function of "Bin Index", which is calculated as follows: Bin Index = (decay position bin index ) × (number of p_T bins × number of decay type bins) + p_T bin index * (number of decay type bin) + decay type bin index. The efficiency for a given pair-produced LLP sample can be obtained by summing the efficiency values for each event as extracted from this map, and dividing it by the total number of events in the sample. The efficiency map is symmetric between the LLPs, so the choice of LLP1 and LLP2 is arbitrary. For the high-E_T selections, for overall efficiencies above 0.5%, the results are typically accurate to around 25%, but below this the efficiency can be overestimated and therefore should not be used for re-interpration.

Mid-rapidity (|y| < 0.1) identified particle spectra in d+Au collisions at 200 GeV. The p and pbar spectra are inclusive, including weak decay products. Spectra are plotted for three centrality bins and for minimum bias events.
