We examine jet shapes in the forward region, {eta}(jet) > 4, of 40 TeV proton-proton collisions and compare them with 90{degree} jets. In the laboratory, forward jets are Lorentz contracted into thin ``disks.`` For example, a jet which at {theta}{sub cm}(jet) = 90{degree} would have its particles located within a ``cone`` with angular widths {Delta}{theta}{sub cm} = {Delta}{phi} = 28{degree} (i.e., 0.5 radians), if ``boosted`` to {eta}(jet) = 4 ({theta}{sub cm} = 2{degree}) becomes a ``disk`` with an angular width of {Delta}{theta}{sub cm} = 1{degree}! Jet shapes are roughly invariant when plotted versus pseudorapidity, {eta}, and azimuthal angle, {phi}. In addition, we examine how well the electromagnetic component (i.e., photons and electrons) of a jet ``tracks`` the true position of the jet.
