NUCLEON PROPERTIES IN NUCLEAR MEDIUM

  • By using the valon model, the electric form factor of the proton in the nucleus GEP(Q2), and π decay constant fπ are discussed. After combining the (e,e') reaction on the 56Fe near the quasielestic peak, it is found that GEP(Q2) and fπ are influnced by the nuclear medium and their modifications result from increased hadron size as the distortions of structure functions (EMC effect) do.

NUCLEON PROPERTIES IN NUCLEAR MEDIUM

Abstract: By using the valon model, the electric form factor of the proton in the nucleus GEP(Q2), and π decay constant fπ are discussed. After combining the (e,e') reaction on the 56Fe near the quasielestic peak, it is found that GEP(Q2) and fπ are influnced by the nuclear medium and their modifications result from increased hadron size as the distortions of structure functions (EMC effect) do.
