英文摘要We present the first measurements of the rho(770)(0),k-*(892),delta(1232)(++),sigma(1385), and lambda(1520) resonances in d+au collisions at s(nn)=200 gev, reconstructed via their hadronic decay channels using the star detector (the solenoidal tracker at the bnl relativistic heavy ion collider). 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 are compared with the < p(t)> of pi,k, and p. the rho(0)/pi(-),k-*/k-,delta(++)/p,sigma(1385)/lambda, and lambda(1520)/lambda ratios in d+au collisions are compared with the measurements in minimum bias p+p interactions, where we observe that both measurements are comparable. the nuclear modification factors (r-dau) of the rho(0),k-*, and sigma(*) scale with the number of binary collisions (n-bin) for p(t)> 1.2 gev/c.
