Title: Gauge mediation at the LHC: status and prospects

Abstract

We show that the predictivity of general gauge mediation (GGM) with TeV-scale stops is greatly increased once the Higgs mass constraint is imposed. The most notable results are a strong lower bound on the mass of the gluino and right-handed squarks, and an upper bound on the Higgsino mass. If the μ-parameter is positive, the wino mass is also bounded from above. These constraints relax significantly for high messenger scales and as such long-lived NLSPs are favored in GGM. We identify a small set of most promising topologies for the neutralino/sneutrino NLSP scenarios and estimate the impact of the current bounds and the sensitivity of the high luminosity LHC. The stau, stop and sbottom NLSP scenarios can be robustly excluded at the high luminosity LHC.

  • In these proceedings I explore one aspect of gauge-boson physics at the LHC--Triple Gauge-boson Couplings (TGCs) in WZ and W{gamma} production. Methods for extracting confidence limits on anomalous TGCs are assessed, while accounting for the effects of higher order QCD corrections and contributions from other theoretical and detector related systematics. Detector response has been parametrised according to the ATLAS detector's specifications. A strategy for reporting the anomalous coupling limits is introduced which removes the ambiguities of form factors by reporting the limits as a function of a cutoff operating on the diboson system invariant mass. Techniques for measuring the energymore » dependence of anomalous couplings are demonstrated.« less
  • We show a calculable example of stable supersymmetry (SUSY) breaking modelswith O(10) eV gravitino mass based on the combination of D-term gauge mediationand U(1)' mediation. A potential problem of the negative mass squared for theSUSY standard model (SSM) sfermions in the D-term gauge mediation is solvedby the contribution from the U(1)' mediation. On the other hand, the splittingbetween the SSM gauginos and sfermions in the U(1)' mediation iscircumvented bythe contributions from the D-term gauge mediation. Since the U(1)' mediation doesnot introduce any new SUSY vacua, we achieve a completely stable model underthermal effects. Our model, therefore, has no cosmological difficulty.
  • A striking consequence of supersymmetry breaking communicated purely via the superconformal anomaly is that the gaugino masses are proportional to the gauge {beta} functions. This result, however, is not unique to anomaly mediation. We present examples of ''generalized'' gauge-mediated models with messengers in standard model representations that give nearly identical predictions for the gaugino masses, but positive (mass){sup 2} for all sleptons. There are remarkable similarities between an anomaly-mediated model with a small additional universal mass added to all scalars and the gauge-mediated models with a long-lived W-ino next-to-lightest supersymmetric particle, leading to only a small set of observables thatmore » provide robust distinguishing criteria. These include ratios of the heaviest to lightest selectrons, smuons, and top squarks. The sign of the gluino soft mass is an unambiguous distinction, but requires measuring a difficult class of one-loop radiative corrections to sparticle interactions. A high precision measurement of the Higgs-boson-b-b(bar sign) coupling is probably the most promising interaction from which this sign might be extracted.

  • Dilepton gauge bosons which appear in a class of unified models are studied both from the point of view of existing data and of future experiments. Present data allow masses only above 120 GeV. Future experiments in {ital e}{sup +}{ital e{minus}} scattering can improve this bound to 600 GeV (CERN {ital e}{sup +}{ital e{minus}} collider LEP II with {radical}{ital s} =200 GeV) and to 1500 GeV (Next Linear Collider {ital e}{sup +}{ital e{minus}} with {radical}{ital s} =500 GeV). The process {ital e}{sup {minus}}{ital e{minus}}{r arrow}{mu}{sup {minus}}{mu}{sup {minus}} could provide an excellent signature for the existence of dilepton gauge bosons inmore » an {ital e}{sup {minus}}{ital e{minus}} collider, even for {radical}{ital s} =100 GeV.« less
