| dc.description | We present the first measurements of the $ρ(770)^0$, $K^*$(892), $Δ$(1232)$^{++}$, $Σ$(1385), and $Λ$(1520) resonances in $d$+Au collisions at $\sqrt{s_{_{NN}}}$ = 200 GeV, reconstructed via their hadronic decay channels using the STAR detector at RHIC. The masses and widths of these resonances are studied as a function of transverse momentum ($p_T$). We observe that the resonance spectra follow a generalized scaling law with the transverse mass ($m_T$). The $<p_T>$ of resonances in minimum bias collisions is compared to the $<p_T>$ of $π$, $K$, and $\bar{p}$. The $ρ^0/π^-$, $K^*/K^-$, $Δ^{++}/p$, $Σ(1385)/Λ$, and $Λ(1520)/Λ$ ratios in $d$+Au collisions are compared to the measurements in minimum bias $p+p$ interactions, where we observe that both measurements are comparable. The nuclear modification factors ($R_{dAu}$) of the $ρ^0$, $K^*$, and $Σ^*$ scale with the number of binary collisions ($N_{bin}$) for $p_T >$ 1.2 GeV/$c$. | |
