A single-molecule stretching method for lateral and normal AFM lever calibration

Giovanni Dietler, Andrzej Kulik, Fabrizio Benedetti

A novel method for quantitative lateral force measurement (LFM) calibration has been developed. Using a single-molecule spectroscopy approach it is possible to calibrate the AFM levers for both lateral and normal spring constants with a single image scan. ...

Long-Range Magnetic Fields in the Ground State of the Standard Model Plasma

Alexey Boyarsky, Oleg Ruchayskiy

In thermal equilibrium the ground state of the plasma of Standard Model particles is determined by temperature and exactly conserved combinations of baryon and lepton numbers. We show that at nonzero values of the global charges a translation invariant and ...

Four-lepton production at hadron colliders: aMC@NLO predictions with theoretical uncertainties

Valentin Hirschi, Paolo Torrielli

We use aMC@NLO to study the production of four charged leptons at the LHC, performing parton showers with both HERWIG and PYTHIA6. Our underlying matrix element calculation features the full next-to-leading order O(alpha(S)) result and the O(alpha(2)(S)) c ...

An interconnection method for ultra-compliant electrodes

Stéphanie Lacour, Katherine Marie Musick

We are developing a novel interconnection method to form reliable joints between truly stretchable electrode mounts and rigid substrates. This is needed as the electrodes must be connected to implanted electronics if they are to be used for long term impla ...

Inclusive W and Z production in the forward region at root s=7TeV

Jian Wang, Olivier Schneider, Yiming Li, Yi Zhang, Aurelio Bay, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Christophe Salzmann, Lei Zhang, Jessica Prisciandaro, Mark Tobin, Minh Tâm Tran, Niko Neufeld, Matthew Needham, Marc-Olivier Bettler, Greig Alan Cowan, Maurizio Martinelli, Vladislav Balagura, Cédric Potterat, Jean Wicht, Ilya Komarov, Plamen Hristov Hopchev, Bastien Luca Muster, Frédéric Guillaume Dupertuis, Julien Rouvinet, Barinjaka Rakotomiaramanana, Pierre Jaton, Joël Bressieux, Raluca Anca Muresan, Songmei Wu, Johan Luisier, Anne Keune, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht, Neal Gauvin, Hans Dijkstra, Gerhard Raven, Peter Clarke, Frédéric Teubert, Giovanni Carboni, Victor Coco, Wenyu Zhang

Measurements of inclusive W and Z boson production cross-sections in p p collisions at root s = 7TeV using final states containing muons are presented. The data sample corresponds to an integrated luminosity of 37 pb(-1) collected with the LHCb detector. T ...

Probing the scattering of equivalent electroweak bosons

Riccardo Rattazzi, Andrea Wulzer, Roberto Franceschini, Pascal Borel

We analyze the kinematic conditions under which the scattering of equivalent massive spin-1 vector bosons factorizes out of the complete process. In practice, we derive the conditions for the validity of the effective W approximation, proposed long ago but ...

First observation of the decay (B)over-bar(S)(0) -> (DK)-K-0(0) and a measurement of the ratio of branching fractions B((B)over-bar(S)(0)->(DK)-K-0(0))/B((B)over-bar(0)-> D-0 rho(0))

Jian Wang, Olivier Schneider, Yi Zhang, Aurelio Bay, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Christophe Salzmann, Lei Zhang, Jessica Prisciandaro, Mark Tobin, Minh Tâm Tran, Niko Neufeld, Matthew Needham, Marc-Olivier Bettler, Greig Alan Cowan, Vladislav Balagura, Cédric Potterat, Plamen Hristov Hopchev, Frédéric Guillaume Dupertuis, Julien Rouvinet, Barinjaka Rakotomiaramanana, Pierre Jaton, Joël Bressieux, Raluca Anca Muresan, Johan Luisier, Anne Keune, Albert Puig Navarro, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht, Neal Gauvin, Géraldine Conti, Hans Dijkstra, Gerhard Raven, Peter Clarke, Frédéric Teubert, Giovanni Carboni, Victor Coco, Wenyu Zhang

The first observation of the decay (B) over bar (0)(S) -> (DK)-K-0*(0) using pp data collected by the LHCb detector at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 36 pb(-1), is reported. A signal of 34.4 +/- 6.8 events is ...

Composite Higgs as a Viable Scenario for Electro-Weak Symmetry Breaking

Jan Dalibor Mrazek

This thesis presents a general discussion of the Composite Higgs scenario of Electro-Weak Symmetry Breaking (EWSB). We start by reviewing the Standard Model of Electro-Weak interaction, discussing its experimental tests and conceptual pitfalls. Emphasis is ...

Statistical analysis of subnanometer residual disorder in photonic crystal waveguides: Correlation between slow light properties and structural properties

Romuald Houdré, Hua Zhang, Nicolas Le Thomas, Zhaolu Diao

The authors present a statistical study of residual disorder in nominally identical planar photonic crystal waveguides operating in the slow light regime. The focus is on the role played by the subnanometer scaled residual disorder inherent to state-of-the ...

Anomaly driven signatures of new invisible physics at the Large Hadron Collider

Alexey Boyarsky, Oleg Ruchayskiy

Many extensions of the Standard Model (SM) predict new neutral vector bosons at energies accessible by the Large Hadron Collider (LHC). We study an extension of the SM with new chiral fermions subject to non-trivial anomaly cancellations. If the new fermio ...
