Can -- Conversion in Nuclei be a Good Probe for Lepton-Number Violating Higgs Couplings ?
Motivated by the improving sensitivity, , of experiments on and the enhanced Higgs nucleon interaction, we study this
lepton number violating process induced by Higgs exchange. Taking the possible
sensitivity, , we obtain the constraint on the
Higgs-muon-electron vertex, , to be less than
if the masses of the Higgs scalar and gauge boson are
the same. is also calculated for some models.Comment: 11 pages(revtex 3), TRI-PP-93-7
Nuclear shadowing in inclusive and tagged deuteron structure functions and extraction of F_2^p-F_2^n at small x from electron-deuteron collider data
We review predictions of the theory of leading twist nuclear shadowing for
inclusive unpolarized and polarized deuteron structure functions F_2^D, g_1^D
and b_1^D and for the tagged deuteron structure function F_2^D(x,Q^2,\vec{p}).
We analyze the possibility to extract the neutron structure function F_2^n from
electron-deuteron data and demonstrate that an account of leading twist nuclear
shadowing leads to large corrections for the extraction of F_2^n from the
future deuteron collider data both in the inclusive and in the tagged structure
function modes. We suggest several strategies to address the extraction of
F_2^n and to measure at the same time the effect of nuclear shadowing via the
measurement of the distortion of the proton spectator spectrum in the
semi-inclusive e D \to e^{\prime}NX process. We address the issue of the final
state interactions in the e D \to e^{\prime}NX process and examine how they
affect the extraction of F_2^n.Comment: 19 pages, 7 figures. Published in Mod. Phys. Lett.
