Search for Higgs boson pair production with one associated vector boson in proton-proton collisions at √s=13 TeV

Popis výsledku v původním jazyce

A search for Higgs boson pair (HH) production in association with a vector boson V (W or Z boson) is presented. The search is based on proton-proton collision data at a center-of-mass energy of 13 TeV, collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 138 fb(-1). Both hadronic and leptonic decays of V bosons are used. The leptons considered are electrons, muons, and neutrinos. The HH production is searched for in the b (b) over barb (b) over bar decay channel. An observed (expected) upper limit at 95% confidence level of VHH production cross section is set at 294 (124) times the standard model prediction. Constraints are also set on the modifiers of the Higgs boson trilinear self-coupling, k(lambda), assuming k(2V) = 1, and vice versa on the coupling of two Higgs bosons with two vector bosons, k(2V). The observed (expected) 95% confidence intervals of these coupling modifiers are -37.7 &lt; k(lambda) &lt; 37.2 (-30.1 &lt; k(lambda) &lt; 28.9) and -12.2 &lt; k(2V) &lt; 13.5 (-7.2 &lt; k(2V) &lt; 8.9), respectively.
