Search for Higgs boson production at high transverse momentum in the WW decay channel in proton-proton collisions at $$ \sqrt{s}=13 $$ TeV
A bstract A search for Higgs boson (H) production at high transverse momentum ( p T ) in the WW decay channel is presented. The analysis uses proton-proton collisions at $$ \sqrt{s}=13 $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> <mml:mo>=</mml:mo> <mml:mn>13</mml:mn> </mml:math> TeV recorded by the CMS experiment in 2016–2018, corresponding to an integrated luminosity of 138 fb − 1 . The visible decay products of the Higgs boson are reconstructed as a single large-radius jet with one isolated lepton or none (1 ℓ and 0 ℓ , respectively; ℓ = e, μ ). The H-candidate jets are identified using an advanced transformer-based algorithm and are calibrated with the Lund jet plane reweighting technique. The 1 ℓ channel is further split into gluon fusion, vector boson fusion, and associated production with hadronically decaying vector boson categories, while the 0 ℓ channel considers all production processes inclusively. The measured cross section times the H → WW branching fraction relative to the standard model expectation is $$ \mu =-{0.19}_{-0.46}^{+0.48} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>μ</mml:mi> <mml:mo>=</mml:mo> <mml:mo>−</mml:mo> <mml:msubsup> <mml:mn>0.19</mml:mn> <mml:mrow> <mml:mo>−</mml:mo> <mml:mn>0.46</mml:mn> </mml:mrow> <mml:mrow> <mml:mo>+</mml:mo> <mml:mn>0.48</mml:mn> </mml:mrow> </mml:msubsup> </mml:math> , indicating no evidence of a signal above the background. This measurement represents the first dedicated study of highly Lorentz-boosted H → WW decays, complementing earlier searches for high- p T Higgs boson in other decay channels.
