Observation of New Resonances Decaying to J=Psi K plus and J=Psi phi

Lesya Shchutska, Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Frédéric Blanc, Christoph Frei, Tatsuya Nakada, Michel De Cian, Elena Graverini

The first observation of exotic states with a new quark content ccus decaying to the J/Psi K+ final state is reported with high significance from an amplitude analysis of the B+-> J/ Psi phi K+ decay. The analysis is carried out using proton-proton collisi ...

First Observation of Excited Omega(-)(b) States

Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Frédéric Blanc, Christoph Frei, Tatsuya Nakada, Michel De Cian, Luca Pescatore, Elena Graverini

We report four narrow peaks in the Xi K-0(b)- mass spectrum obtained using pp collisions at center-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb(-1) recorded by the LHCb experiment. Referring to these states b ...

Resistive Coupled VO2 Oscillators for Image Recognition

Mihai Adrian Ionescu, Igor Stolichnov, Kirsten Emilie Moselund, Siegfried Karg, Elisabetta Corti

Oscillator networks are known for their interesting collective behavior such as frequency locking, phase locking, and synchronization. Compared to other artificial neural network implementations, timing rather than amplitude information is used for computa ...

Mutually Coupled Time-to-Digital Converters (TDCs) for Direct Time-of-Flight (dTOF) Image Sensors

Edoardo Charbon, Preethi Padmanabhan, Augusto Ronchini Ximenes

Direct time-of-flight (dTOF) image sensors require accurate and robust timing references for precise depth calculation. On-chip timing references are well-known and understood, but for imaging systems where several thousands of pixels require seamless refe ...

Simultaneous High-Speed High-Resolution Nanomechanical Mass Sensing

Maher Kayal, Marc Pastre, Christian Kauth

Mass sensing has so far rather developed along the resolution axis, reaching atomic-scale detection, than into the direction of high speed. This letter reports on a novel self-calibrating technique that makes high-speed inertial mass sensors capable of ins ...

Observation of e(+)e(-) -> pi(+)pi(-) pi(0)chi(bJ) and Search for X-b -> omega Upsilon(1S) at root s=10.867 GeV

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Tara Nanut, Donghyun Kim, Xiao Wang

The e(+)e(-) -> pi(+)pi(-) pi(0)chi(bj) ( J = 0, 1, 2) processes are studied using a 118 fb(-1) data sample acquired with the Belle detector at a center-of-mass energy of 10.867 GeV. Unambiguous pi(+)pi(-) pi(0)chi(bj) ( J = 1, 2), omega chi(b1) signals ar ...
