Higgs Decays to Muons in Weak Boson Fusion
نویسندگان
چکیده
We investigate the muonic decay of a light Higgs boson, produced in weak boson fusion at future hadron colliders. We find that this decay mode would be observable at the CERN LHC only with an unreasonably large amount of data, while at a 200 TeV vLHC this process could be used to extract the muon Yukawa coupling to about the 10% level, or better if significant improvements in detector design can be achieved.

Maximum Significance at the LHC and Higgs Decays to Muons
We present a new way to define and compute the maximum significance achievable for signal and background processes at the LHC, using all available phase space information. As an example, we show that a light Higgs boson produced in weak–boson fusion with a subsequent decay into muons can be extracted from the backgrounds. We generalize our method to include detector effects and reducible backgr...
متن کاملSearching for H → ττ in weak boson fusion at the LHC
Weak boson fusion is a copious source of intermediate mass Higgs bosons at the LHC. The additional very energetic forward jets in these events provide for powerful background suppression tools. We analyze the H → τ τ decay mode for the Standard Model Higgs boson. A parton level analysis of the dominant physics backgrounds (mainly Z → τ τ and Drell-Yan production of τ 's) and of reducible backgr...
متن کاملIdentifying the Higgs Spin and Parity in Decays to Z Pairs
Higgs decays to Z boson pairs may be exploited to determine spin and parity of the Higgs boson, a method complementary to spin–parity measurements in Higgs-strahlung. For a Higgs mass above the on-shell ZZ decay threshold, a model-independent analysis can be performed, but only by making use of additional angular correlation effects in gluon-gluon fusion at the LHC and γγ fusion at linear colli...
متن کاملHiggs Production via Gluon-Induced Weak Boson Fusion
One of the primary goals of the CERN Large Hadron Collider (LHC) that will go into full operation soon is to illuminate the electro-weak symmetry breaking mechanism. The favoured mechanism — the Higgs mechanism — predicts the existence of a Higgs boson. The Higgs boson will be produced at the LHC mainly through gluon fusion which has the largest cross section there. While for Higgs masses of mH...

A search for a two-body transition Υ (3S) → γA0, where A0 is a light scalar particle, followed by its decay into 2 muons has been performed using a data sample of (121 ± 1.2) × 106 Υ (3S) decays. As ΓΥ (4S)/ΓΥ (3S) ≈ 10 3, one has greater sensitivity to rare decays using Υ (3S) decays than Υ (4S) samples. The Standard Model (SM) predicts the existence of the Higgs boson to account for the diffe...
