The single electron track-reconstruction efficiency is calibrated using a sample corresponding to 1.3 fb(-1) of pp collision data recorded with the LHCb detector in 2017. This measurement exploits B+ -> J/psi (e(+)e(-))K+ decays, where one of the electrons ...

Calculating Optimistic Likelihoods Using (Geodesically) Convex Optimization

Daniel Kuhn, Wolfram Wiesemann, Viet Anh Nguyen, Soroosh Shafieezadeh Abadeh

A fundamental problem arising in many areas of machine learning is the evaluation of the likelihood of a given observation under different nominal distributions. Frequently, these nominal distributions are themselves estimated from data, which makes them s ...

Uncertainty reduction in biochemical kinetic models: Enforcing desired model properties

Vassily Hatzimanikatis, Ljubisa Miskovic, Michaël Roger Germain Moret

A persistent obstacle for constructing kinetic models of metabolism is uncertainty in the kinetic properties of enzymes. Currently, available methods for building kinetic models can cope indirectly with uncertainties by integrating data from different biol ...

Search for the rare decay B+ -> mu(+) mu(-) mu(+)nu(mu)

Jian Wang, Olivier Schneider, Zhirui Xu, Yiming Li, Lei Zhang, Yi Wang, Aurelio Bay, Guido Haefeli, Jessica Prisciandaro, Tatsuya Nakada, Christoph Frei, Mark Tobin, Frédéric Blanc, Minh Tâm Tran, Greig Alan Cowan, Maurizio Martinelli, Vladislav Balagura, Donal Patrick Hill, Pietro Marino, Luca Pescatore, Mirco Dorigo, Jean Wicht, Liupan An, Elena Graverini, Federico Leo Redi, Chitsanu Khurewathanakul, Plamen Hristov Hopchev, Renato Quagliani, Maxime Schubiger, Hang Yin, Guido Andreassi, Violaine Bellée, Maria Vieites Diaz, Olivier Göran Girard, Axel Kuonen, Preema Rennee Pais, Aravindhan Venkateswaran, Pavol Stefko, Tara Nanut, Maria Elena Stramaglia, Luis Miguel Garcia Martin, Tommaso Colombo, Vladimir Macko, Vitalii Lisovskyi, Mingkui Wang, Guillaume Max Pietrzyk, François Fleuret, Yi Zhang, Liang Sun, Ian William Marison, Michael Thompson McCann, Valérie Jeanne Thérèse Renaudin-Schouler, Craig Matthew Smith, Bjorn Jozef Maria Robroek, Juan Federico Esteban Müller, John Martin Kolinski, Achille Mauri, Basil Andrew Stansfield Davis, Mercedes Hannelore Rittmann-Frank, Jorge Miguel Dias Almeida Rodrigues Soares, Remy Jean Henry Albrecht, Chia-Chun Chen

A search for the rare leptonic decay B +. mu + mu - mu +.mu is performed using proton- proton collision data corresponding to an integrated luminosity of 4.7 fb - 1 collected by the LHCb experiment. The search is carried out in the region where the lowest ...

Exponential Collapse Of Social Beliefs Over Weakly-Connected Heterogeneous Networks

Ali H. Sayed, Augusto José Rabelo Almeida Santos

We consider a distributed social learning problem where a network of agents is interested in selecting one among a finite number of hypotheses. The data collected by the agents might be heterogeneous, meaning that different sub-networks might observe data ...

Search for Lepton Number Violating Decays B+ -> pi(-)mu(+)mu(+) and B+ -> K-mu(+)mu(+)

Jian Wang, Olivier Schneider, Yi Zhang, Lei Zhang, Aurelio Bay, Guido Haefeli, Jessica Prisciandaro, Tatsuya Nakada, Christoph Frei, Mark Tobin, Frédéric Blanc, Minh Tâm Tran, Michel De Cian, Greig Alan Cowan, Vladislav Balagura, Plamen Hristov Hopchev, Frédéric Guillaume Dupertuis, Julien Rouvinet, Christophe Salzmann, Pierre Jaton, Barinjaka Rakotomiaramanana, Joël Bressieux, Raluca Anca Muresan, Johan Luisier, Albert Puig Navarro, Anne Keune, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht, Neal Gauvin

A search is performed for the lepton number violating decay B+ -> h(-)mu(+)mu(+), where h(-) represents a K- or a pi(-), using an integrated luminosity of 36 pb(-1) of data collected with the LHCb detector. The decay is forbidden in the standard model but ...
