WebOct 1, 2007 · The transferred polarization in the 4He (~e, e0~p )3H reaction at Q2 values of 0.4, 0.5, 1.0, 1.6, and 2.6 GeV2 have been measured to study possible medium modifications of the proton form factors. The measured ratio of polarization-transfer coefficients was described by the inclusion of in-medium proton form factors. Web808 Appendix A Spinor Representation It is easy to show that s and v behave like a scalar and a vector, namely as spin 0 and 1 particles. From the above arguments, we realize that SU(2) operation on and that of O(3) on vector (x, y,z) are closely related.Writing down explicitly operations on spin part U D e iσ θ/2 D cos θ 2 sin θ 2 iσ n, R D e iJ θ D cosθ sin …
