Search for high-mass exclusive diphoton production with tagged protons in proton-proton collisions at √s=13 TeV

Matthias Finger, Qian Wang, Varun Sharma, Konstantin Androsov, Jan Steggemann, Ian Smith, Xin Chen, Rakesh Chawla, Michele De Palma, Matteo Galli

A search is presented for high-mass exclusive diphoton production via photon-photon fusion in proton-proton collisions at root s = 13 TeV in events where both protons survive the interaction. The analysis utilizes data corresponding to an integrated lumino ...

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 ...

A 3D Microscaffold Cochlear Electrode Array for Steroid Elution

Jürgen Brugger, Joo Yeon Kim, Jongmoon Jang

In cochlear implants, the electrode insertion trauma during surgery can cause damage residual hearing. Preserving the residual hearing is an important challenge and the localized administration of drugs, such as steroids, is one of the most promising ways, ...

The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2016 follow-up campaign - I. Overview and classification of candidates selected by two techniques

Eduardo Sanchez, Frédéric Courbin, Georges Meylan, Riccardo Agnello, Joo Yeon Kim, Hung-Hsu Chan, Augusto Martins Lima, Karina Alexandra Rojas Olate, Craig Matthew Smith, Cameron Alexander Campbell Lemon

The primary goals of the STRong lensing Insights into the Dark Energy Survey (STRIDES) collaboration are to measure the dark energy equation of state parameter and the free streaming length of dark matter. To this aim, STRIDES is discovering strongly lense ...

Observation of the rare B-s(0)->mu(+)mu(-) decay from the combined analysis of CMS and LHCb data

Matthias Finger, Lesya Shchutska, Olivier Schneider, Aurelio Bay, Guido Haefeli, Qian Wang, Frédéric Blanc, Yiming Li, Tatsuya Nakada, Varun Sharma

The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested experimentally. The probabilitie ...

Simple and easily controllable parabolic-shaped microlenses printed on polymeric mesas

Jürgen Brugger, Joo Yeon Kim, Cristina Martin Olmos

A simple and easy shape-controllable approach is demonstrated for the fabrication of parabolic-shaped polymer microlenses (mu-lenses), which are widely used in bio-imaging systems such as microfluidic and lab-on-a-chip systems for improving the image quali ...

Directly fabricated multi-scale microlens arrays on a hydrophobic flat surface by a simple ink-jet printing technique

Jürgen Brugger, Joo Yeon Kim

A shape-tunable approach is demonstrated for the fabrication of multi-scale polymer microlenses ([small mu ]-lenses) and microlens arrays (MLAs) using an ink-jet printing (IJP) technique. Also, the influence of the surface wetting conditions on the geometr ...

Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique

Jürgen Brugger, Edoardo Charbon, Vahid Fakhfouri, Dmitri Boiko, Joo Yeon Kim, Nils Benedict Brauer

Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we de ...
