Experimental Program at JLAB Compare F 2 in DIS off high-momentum nucleons to F 2 of free nucleons E12-11-107 – TAU, ODU, MIT JLAB Experimental method Use deuteron as a target in DIS Tag high-momentum nucleons with high-momentum backwardrecoiling (“spectator”) partner nucleon as in SRC using the reaction d(e,e’N S )
Experimental Method Utilize factorization of the d(e,e’N S ) cross section to SF and distorted momentum distribution. Keeping the recoil kinematics fixed and measuring x-section ratios at 2 different χ’, the ratio is: d 4 ! d" 1 dQ 2 d p ! d 4 ! S d" 2 dQ 2 d p ! = ( K 1 K 2 )"# F ! 2 (! 1 '," S , p T ,Q 2 1 ) F ! 2 (! 2 '," S , p T ,Q 2 1 ) $ % S For χ 1 ’≈0.45 – 0.6 and χ 2 ’≈0.3 we shall measure: " d 4 # F ! 2 (! 1 '," S , p T ,Q 2 1 ) F ! 2 (! 2 '," S , p T ,Q 2 1 ) = d! 1 dQ 2 d p ! % / K 1 # $ S & ' " d 4 ! d" 2 dQ 2 d p ! % / K 2 # $ S & ' Integraang over θ pq > 107° (small FSI), we’ll compare the measured raao f(α S ) to the BONUS results for free neutron, and to the free proton SF in d(e,e’n S )
