Forward GEM Tracker (FGT) at STAR
ORAL
Abstract
As part of our program to understand the internal structure of the proton, we have and will continue mid-rapidity ($-1<\eta<1$) W and di-jet measurements in p+p collisions at $\sqrt{s} = 500GeV$. The ongoing STAR W program is exploring the longitudinal spin contribution of anti-u and anti-d quarks to the proton spin. The gluon spin contribution can be probed through di-jet measurements. The Forward GEM Tracker (FGT) at STAR will enhance the charged sign separation for high $p_{T}$ tracks in the pseudo-rapidity range of $1.0<\eta<2.0$, and therefore allows an extension of W and di-jet measurements at forward pseudo-rapidity. We will present the status of the FGT assembly and completion along with projections for future W and di-jet measurements. We will discuss studies that explore the possibilities of using the FGT to reconstruct jets in the forward direction.
