“…The isoscalar nature of the deuteron allows to get a simple expression for the P-even asymmetry in the scattering of longitudinally polarized electrons by unpolarized deuterons which does not depend on the details of the deuteron structure, in the framework of the Standard Model [43,44,45]. The generalization of this result has been recently done in the case of inelastic electroproduction of pion on nucleon [46].…”

The constraints from the 7r, 2 decay experiment [9,10], the p measurement [8], and the nuclear 8-decay experinlent [6,7] Here, IH and CH are, respectively, the isotropic and cosine terms of the pure V-A muon decay with heavy neutrino emission, which were formulated by Rekalo [46]. With these formula, the limits on mw, as a function of the UR mass were evaluated as shown in Fig In the case of m,, 2 50 MeV/c2, the decay muon coupled with the v~ has a lower momentum than the momentum acceptance of the present beam line; P, thus definitely equals -1.…”

The asymmetry of positrons in the K+ -t p+v, p+ + e+vei7, decay chain was measured in a search for right-handed weak currents in AS = 1 semileptonic decay. High-intensity low-background monoenergetic polarized muons of 236 MeV/c momentum resulting from kaon decay at rest were directly extracted from a primary production target which was hit by a proton beam of the KEK 12-GeV proton synchrotron. Muons were stopped in a pure-aluminum plate, and the energy-integrated asymmetry of the decay positrons with respect to the incoming muon direction was determined to high precision. The observed asymmetry yielded ( P , = -0.9996 2c 0.0030(stat) f 0.0048(syst). This result revealed no evidence of right-handed currents in this kaon-decay chain, and set a stringent bound on the mass of the right-handed weak boson.

AOKI et al. 50 to the conventional weak boson (WL), they assume another weak intermediate boson (WR) which couples to the right-handed weak currents, replacing the standard gauge group s U ( 2 )~ @ U(1) with s U ( 2 )~ @ SU(2)R 8 % U(1). In general, these weak bosons are a superposition of mass eigenstates ( W I ,~) , which can be written as WL = WI cos 6 + W2 sin C, WR = -Wl sin C + W2 cos (, where 6 is the mixing angle. Then, the left handedness in the low-energy region can be attributed to mw, >> mw; and/or the smallness of C, where mw, is the mass of W,.That is, right-handed phenomena in the low-energy region are suppressed by c2 = (mw, /mw2)*. Regarding the coupling of WR to a quark c G r e n t , a right-handed Cabibbo angle (OR), which is an analogue to the ordinary Cabibbo angle (OL) [23], is also introduced. Although manifest LRS models [24] require that sineR = singL, nonequality (sineR # sineL) can be postulated in general [25,26,161. 1n-the case-of manifest left-right symmetry, there is no physical difference between the kaon-and the pion-decay positron-asymmetry experiments. However, if OR # OL and I sin OR I -. 1. the kaon decay experiments are very

Dependences of the azimuthal and target asymmetries in the breakup of polarized deuterons by unpolarized electrons on the choice of the deuteron electromagnetic (EM) current model and finalstate interaction (FSI) efFects are investigated. Possibilities for separation of the structure functions which determine these observables are discussed. Results of the calculations are compared with available data. It has been shown that FSI plays an important role in formation of the asymmetries.In the quasifree region some of them depend considerably on the neutron electric form factor and on the spin-orbit EM interaction with nucleon. The tensor target asymmetries T2o and T&2 calculated for H(e, pn)e' under kinematic conditions of the experiment with the electron storage ring VEPP -3 in Novosibirsk have been found to be very sensitive to the meson exchange current contributions.PACS number(s): 25.30.
