Measurement of the tt¯ production cross section in the all-jets final state in pp collisions at √s = 8 TeV
(2016-03-08)
The cross section for tt¯ production in the all-jets final state is measured in pp collisions at a centre-of-mass energy of 8 TeV at the LHC with the CMS detector, in data corresponding to an integrated luminosity of 18.4 ...
Measurement of top quark polarisation in t-channel single top quark production
(2016-04-13)
A first measurement of the top quark spin asymmetry, sensitive to the top
quark polarisation, in t-channel single top quark production is presented. It is based on a
sample of pp collisions at a centre-of-mass energy of ...
