| dc.description.abstract | A search for heavy resonances decaying to a pair of Higgs bosons in the four b
quark final state is presented. The analysis is based on the data collected in 2016
with the CMS detector at LHC at center-of-mass energy √
s = 13 TeV, corresponding
to integrated luminosity of 35.9 f b−1
. The Higgs bosons are reconstructed
from high momentum b
¯b quark pairs. The mass variable, τ21 discriminator, and
double-b tagger are used for Higgs tagging. The signal regions are separated by
double-b tagger into two categories. A 95% upper limit on the production cross
section of σX × B(X → HH → b
¯bb¯b) is obtained from the combination of two
categories with a limit below 10 fb for mX from 1200 to 3000 GeV | en_US |
