We study the effect of charged secondaries coming from resonance decay on the
net-baryon, net-charge and net-strangeness fluctuations in high energy
heavy-ion collisions within the hadron resonance gas (HRG) model. We emphasize
the importance of including weak decays along with other resonance decays in
the HRG, while comparing with the experimental observables. The effect of
kinematic cuts on resonances and primordial particles on the conserved number
fluctuations are also studied. The HRG model calculations with the inclusion of
resonance decays and kinematical cuts are compared with the recent experimental
data from STAR and PHENIX experiments. We find a good agreement between our
model calculations and the experimental measurements for both net-proton and
net-charge distributions.Comment: 9 pages, 5 figures, Accepted for publication in Physical Review
