Measurement of the 12C(e,e'p)11B Two-Body Breakup Reaction at High Missing Momentum Values

TL;DR

This study measures the 12C(e,e'p)11B reaction cross section at high missing momentum, comparing results with theoretical models and extending the momentum range of existing data.

Contribution

It provides new experimental data on the 12C(e,e'p)11B reaction at missing momenta up to 400 MeV/c, testing theoretical models at higher momentum values.

Findings

Theoretical models agree with data up to 325 MeV/c

Data extends the momentum range of previous measurements

Discrepancies appear between models and data at higher missing momenta

Abstract

The five-fold differential cross section for the 12C(e,e'p)11B reaction was determined over a missing momentum range of 200-400 MeV/c, in a kinematics regime with Bjorken x > 1 and Q2 = 2.0 (GeV/c)2. A comparison of the results and theoretical models and previous lower missing momentum data is shown. The theoretical calculations agree well with the data up to a missing momentum value of 325 MeV/c and then diverge for larger missing momenta. The extracted distorted momentum distribution is shown to be consistent with previous data and extends the range of available data up to 400 MeV/c.
