Precision jet substructure from boosted event shapes.
Jet substructure has emerged as a critical tool for LHC searches, but studies so far have relied heavily on shower Monte Carlo simulations, which formally approximate QCD at the leading-log level. We demonstrate that systematic higher-order QCD computations of jet substructure can be carried out by boosting global event shapes by a large momentum Q and accounting for effects due to finite jet s...
متن کاملHiggs Boson Discovery with Boosted Trees
The discovery of the Higgs boson is remarkable for its importance in modern Physics research. The next step for physicists is to discover more about the Higgs boson from the data of the Large Hadron Collider (LHC). A fundamental and challenging task is to extract the signal of Higgs boson from background noises. The machine learning technique is one important component in solving this problem. ...
متن کاملApplication of Jet Trimming in Boosted Higgs Search∗
We present the study of the WH and ZH search with the Higgs Boson decayed to bb̄ at the Large Hadron Collider. The Higgs Boson and the Vector Boson are required to be boosted, and the Higgs Boson is reconstructed with Jet Trimming Technique. The statistical significance for 30fb−1 data is 4.5 σ, which is comparable to the previous result [6].
متن کاملHiggs Properties in the Fourth Generation MSSM : Boosted Signals Over the 3 G Plan ∗
The generalization of the MSSM to the case of four chiral fermion generations (4GMSSM) can lead to significant changes in the phenomenology of the otherwise familiar Higgs sector. In most of the 3GMSSM parameter space, the lighter CP-even h is ∼ 115 − 125 GeV and mostly Standard Model-like while H,A,H are all relatively heavy. Furthermore, the ratio of Higgs vevs, tan β, is relatively unconstra...
متن کامل"active Boosted Learning" Active Boosted Learning (actboost)
Active learning deals with the problem of selecting a small subset of examples to label, from a pool of unlabeled data, for training a good classifier. We develop an active learning algorithm in the boosting framework. In contrast to much of the recent efforts, which has focused on selecting the most ambiguous unlabeled example to label based on the current learned classifier, our algorithm sel...
