High-mass muon pairs from the interaction of proton beam with various liquid and solid targets were detected in a newly constructed spectrometer. The primary goal of the experiment is to study the sea quark contents in nucleons and nuclei. In particular, the Drell-Yan cross-section ratios for liquid deuterium over hydrogen will allow the measurement of sea quark asymmetry, $\\bar{d}/\\bar{u}$, for Bjorken-{\\it x} ranging from 0.1 to 0.45, extending the measurements of the previous experiment NuSea/E866. Improved statistics expected at SeaQuest for ${\\it x}>0.25$ will allow us to check the surprising behaviour of $\\bar{d}/\\bar{u}$ at large {\\it x} observed in NuSea. Additionally, SeaQuest data also provides the opportunity to study other very interesting physics. One such physics is the absolute p+d and p+p Drell-Yan differential cross-section ($M^3d^2\\sigma/dMdx_F$). The measurement of the Drell-Yan cross-section allows improved constraints on the magnitude and shape of sea and valence parton distribution functions (PDFs). In particular, the p+d measurement is sensitive to the $\\bar{d}(x)+\\bar{u}(x)$ distribution. This quantity is required for extracting $\\bar{d}(x)-\\bar{u}(x)$ from $\\bar{d}(x)/\\bar{u}(x)$. The current global PDFs for light sea quarks are very poorly constrained beyond Bjorken-{\\it x} $>$ 0.3. SeaQuest coverage in dimuon mass ($M_{\\mu^-\\mu^+}$) ranging from 4.2 GeV to 8.8 GeV (equivalently $\\sqrt{\\tau}$ in range 0.3 to 0.9 ) and Feynman-{\\it x} ($x_F$) ranging from 0 to 0.8 will extend the measurement from NuSea. Current results are presented in chapter 5. A comparison of E866 p+d and E772 p+d measurement is presented in chapter 8.
