Measurement of the inclusive and differential t(t)over-bar gamma cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at root s=13 TeV

Matthias Finger, Varun Sharma, Olivier Martin, Ian Smith, Jean-François Carlin, Arvind Shah, Rakesh Chawla, Thomas Mountford, Chao Wang, João Miguel das Neves Duarte

The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e(+/-)mu(-/+), e(+)e(-), or mu(+)mu(-)). The measurement is performed using 138 ...

Electrically conducting probes with full tungsten cantilever and tip for scanning probe applications

Jürgen Brugger, Andrzej Kulik, Giovanni Boero, Johannes Steen, Florian Calame, Kyumin Lee

We have developed a new hybrid AFM probe combining an SU-8 polymer body with a full tungsten cantilever having a nanometric tip. The fabrication is based on surface micromachining a silicon wafer, where tungsten is sputter deposited in oxidation sharpened ...

Microfabricated electrically conducting and wear-resistant nanoprobes for scanning probe applications

The era of scanning probe microscopy (SPM) started twenty years ago. A cut gold cantilever with a glued diamond stylus served as the scanning probe. Within a few years the crystalline silicon (Si) became the – up to today – predominant SPM probe material. ...
