Table 4: Reach in m~ g via various event topologies for R-parity violating SUGRA-inspired MSSM, assuming an integrated luminosity of 0.1 fb?1 (1 fb?1), at the Tevatron collider. We use mt = 150 GeV for the background. In a), we show results for B-violating interactions, while in b) we show results for L-violating interactions.case

"... In PAGE 38: ...ecay are simulated exactly as in Sec. 6.1, with the same detector characteristics. The resulting mass reach is listed in Table4 . We see that there is almost no reach in the E/T channel, even given the Main Injector integrated luminosity of 1 fb?1.... In PAGE 39: ... In this case, four addi- tional hard, potentially isolated leptons can exist in the nal state. The reach is again listed in Table4 . We see that in the isolated multilepton channels, very large reaches in m~ g are possible.... In PAGE 39: ... We see that in a), the summed strong production of ~ g~ g + ~ g~ q + ~ q~ q is the dominant cross section over the complete range of m~ g all the way up to 2 TeV. In case b), however, we see that the chargino/neutralino pair production reactions become the dominant SUSY particle production mechanism 12Again, it should be kept in mind that the reaches in Table4 have been obtained with lt; 0.... ..."

We observe that inclusion of additional exchanges plays a major role in reducing the p/n ratio from its pion-only-exchange value.... In PAGE 33: ... which clearly indicates the importance of inclusion of non-pion-exchange components in predicting the p/n ratio. A second strong indication of the presence of non-pion-exchange can be seen from Table9 in that the ratio of rates for parity-violating to parity- conserving transitions is substantially enhanced by the inclusion of kaon and vector meson exchange as compared to the simple pion-exchange-only cal- culation. We can further quantify this e ect by calculating explicitly the angular distribution of the emitted proton in the p ! np transition (there can be no asymmetry for the corresponding n ! nn case due to the identity of the nal state neutrons), yielding Wp( ) 1+ P cos (87) where = R NkF 0 p2dpq p3 2 Ref (p2c + d) R NkF 0 p2dpq 1 4(jaj2 + jbj2 +3jcj2+3jdj2+3jej2+3jfj2 (88) is the asymmetry parameter.... ..."

"... In PAGE 7: ... Similarly as the leptoquark Yukawa couplings L;R from Table 1, these couplings are strongly constrained by existing data. The relevant bounds are summarized in Table2 . As already pointed out, since the excess of events was observed in e+p but not in e?p scattering, the process of class (6) involving the u sea is unlikely.... ..."

Table 1: Scalar (S) and vector (V ) leptoquarks, and their electric charges Q, decay modes, branching ratios into charged lepton + jet channels, and Yukawa couplings. Given are also the most stringent low-energy bounds and the couplings deduced from the 1994-96 HERA data 18. Inclusion of the 1997 data decrease the couplings by about 15%. Using the H1 data alone would roughly give the couplings shown above. Also shown are the possible assignments of squarks with R-parity violating couplings.

in Theoretical Interpretations Of The HERA High-Q² Events
by R. Ruckl, H, Spiesberger
"... In PAGE 3: ... The above constraints follow from pair-production mainly by q q annihilation, and are therefore practically independent of the unknown Yukawa coupling . In contrast, the mass limits obtained at HERA depend on and the quantum numbers speci ed in Table1 . For = e they range from 207 to 272 GeV 13.... In PAGE 5: ... Moreover, with such strong couplings, F = 2 leptoquarks should have shown up in e?p scattering at HERA 20, where they can be produced o the valence quark component, despite of the low luminosity of the previous e?p run. Since vector leptoquarks cannot be made responsible for an excess of events at M apos; 200 to 225 GeV because of the high Tevatron mass bounds, only the two scalar doublets S1=2 and ~ S1=2 remain from the whole Table1 as a possible interpretation. However, also these solutions have di culties.... In PAGE 7: ...ERA data for Q2 gt; 20; 000 GeV2 (from Ref. 27).
