QCD&EW III
- Ciaran Williams (SUNY Buffalo)
The LHC is exploring electroweak (EW) physics at the scale EW symmetry is broken. As the LHC and new high energy colliders push our understanding of the Standard Model to ever-higher energies, it will be possible to probe not only the breaking of but also the restoration of EW symmetry. We propose to observe EW restoration in double EW boson production via the convergence of the Goldstone...
Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the gluons and third generation quarks with masses light enough to be produced at the LHC. This talk will present the latest results...
The direct production of electroweak SUSY particles, including sleptons, charginos, and neutralinos, is a particularly interesting area with connections to dark matter and the naturalness of the Higgs mass. The small production cross sections lead to difficult searches, despite relatively clean final states. This talk will highlight the most recent results of searches performed by the ATLAS...
Measurements of processes involving multiboson final states constitute a precision test of the Standard Model. Moreover, discrepancies between theoretical predictions and experimental measurements could hint to new physics through the presence of anomalous gauge couplings. These processes are also dominant backgrounds for Higgs boson measurements, and searches for new particles with diboson...
The study of the associated production of vector bosons and jets constitutes an excellent environment to check numerous QCD predictions. Total and differential cross sections of vector bosons produced in association with jets have been studied at CMS. Differential distributions as a function of a broad range of kinematical observables are measured and compared with theoretical predictions....
We study the $\mathcal{O}(1/\Lambda^4)$ effects on Drell-Yan process within the framework of the Standard Model Effective Field Theory (SMEFT). By analysing the high energy behavior of the cross sections as functions of SMEFT expansion parameters $\{s,v^2\}/\Lambda^4$, we select operators with dominating contribution to the cross sections at higher scale. The dependence of the cross section on...
