Combination of Searches for Higgs Boson Pair Production in Proton-Proton Collisions at s =13 TeV
(Physical Review Letters, 2019)
This Letter describes a search for Higgs boson pair production using the combined results from four final states: bbγγ, bbττ, bbbb, and bbVV, where V represents a W or Z boson. The search is performed using data collected ...
Spin Excitations in a 4f−3d Heterodimer on MgO
(Physical Review Letters, 2018)
We report on the magnetic properties of HoCo dimers as a model system for the smallest intermetallic compound of a lanthanide and a transition metal atom. The dimers are adsorbed on ultrathin MgO(100) films grown on Ag(100). ...
