Robust new physics searches with unknown backgrounds

نویسندگان

چکیده

Searches for new physics often face unknown backgrounds, causing false detections or weakened upper limits. This paper introduces the ``deficit hawk'' technique, which mitigates backgrounds by testing multiple options data cuts, such as fiducial volumes energy thresholds. Combining power of likelihood ratios with robustness interval-searching techniques, deficit hawks could improve mean limits on a factor 2 experiments partial speculative background knowledge. Deficit are well suited to analyses that use machine learning other multidimensional discrimination techniques and can be extended permit discoveries in regions without background.

CDF Searches for New Physics with Photons

We present results of searches for new physics in final states with photons at CDF in approximately 1fb of pp̄ collisions at 1.96 TeV. We give an overview of the data-driven photon background estimation techniques used for the analyses. We report on a search for diphoton peaks and signature-based searches for γγ +X, lγ +X (X = e, μ, 6ET, γ) and tt̄γ. PACS. 13.85.Rm Limits on production of particl...

Searches for New Physics at the Tevatron

This paper summarizes searches at the Fermilab Tevatron for a wide variety of signatures for physics beyond the Standard Model. These include searches for supersymmetric particles, in the two collider detectors and in one fixed target experiment. Also covered are searches for leptoquarks, dijet resonances, heavy gauge bosons, and particles from a fourth generation, as well as searches for devia...
