AbstractAbstract
[en] The rate and corresponding gluon jet energy distribution for the process e+e- → t anti tg are sensitive to the presence of anomalous dipole-like couplings of the top to the photon and Z at the production vertex as well as to the gluon itself. For sizeable anomalous couplings substantial derivations in the shape and magnitude of the gluon spectrum from the expectations of the Standard Model are anticipated. The authors explore the capability of the Next Linear Collider to either discover or place bounds on these types of top quark couplings through measurements of the gluon energy distribution. The resulting constraints are found to be quite complementary to those obtained using other techniques

AbstractAbstract
[en] We begin to analyze and contrast the predictions for the decay b → sl+l- in the Left-Right Symmetric Model (LMR) with those of the Standard Model (SM). In particular, we show that the forward-backward asymmetry of the lepton spectrum can be used to distinguish the SM from the simplest manifestation of the LRM

AbstractAbstract
[en] Attempts to understand the recent observation of an excess of events in the neutral and charged current channels at high-Q2 at HERA has provided an excellent example of how experiments at both low and high energies can be used to simultaneously constrain scenarios which predict new physics beyond the Standard Model. In this talk the author discusses this subject from the point of view of the construction of new models of leptoquarks

AbstractAbstract
[en] The capability of the NLC in the γe collider mode to probe the CP-conserving γWW and γZZ anomalous couplings through the use of the polarization asymmetry is examined. When combined with other measurements, very strong constraints on both varieties of anomalous couplings can be obtained. The author shows that these bounds are complementary to those that can be extracted from data taken at the LHC

AbstractAbstract
[en] The author summarizes the results of the New Gauge Boson Subgroup on the physics of extended gauge sectors at future colliders as presented at the 1996 Snowmass workshop. He discusses the direct and indirect search reaches for new gauge bosons at both hadron and lepton colliders as well as the ability of such machines to extract detailed information on the couplings of these particles to the fermions and gauge bosons of the Standard Model. 41 refs., 18 figs., 5 tabs

AbstractAbstract
[en] A recent analysis has shown that it may be possible at the SSC to extract information about Z' couplings via the decay Z' → jj. This technique was found to be useful for some extended electroweak models provided the Z' is relatively light. In the present paper, the authors generalize this procedure to the LHC and to Z''s which are more massive than 1 TeV

AbstractAbstract
[en] The recent observation by the CLEO Collaboration of the inclusive decay b → sγ with a branching fraction consistent with the expectations of the Standard Model is used to constrain the parameter space of the Left-Right Symmetric Model. Two scenarios are considered: (1) equal left- and right-handed Cabibbo-Kobayashi-Maskawa mixing matrices, VL = VR(or VR*) and (2) the Gronau-Wakaizumi model wherein B-decays proceed only via right-handed currents and VL and VR are quite distinct. In the later case the bounds from b → sγ are combined with other constraints leaving a parameter range that is very highly restricted and which implies that this model may soon be completely ruled out by improving data
