Search for heavy neutral leptons in decays of W bosons produced in 13 TeV pp collisions using prompt and displaced signatures with the ATLAS detector
(Springer, 2019-10)
The problems of neutrino masses, matter-antimatter asymmetry, and dark matter could be successfully addressed by postulating right-handed neutrinos with Majorana masses below the electroweak scale. In this work, leptonic ...
Measurement of KS0 and Λ production in tt¯ dileptonic events in pp collisions at √s= 7 TeV with the ATLAS detector
(Springer, 2019-12)
Measurements of K0 S and 0 production in tt ¯ final states have been performed. They are based on a data sample with integrated luminosity of 4.6 fb−1 from proton– proton collisions at a centre-of-mass energy of 7 TeV, ...
