Coherent Λπ− production on Pb of 600GeV Σ− hyperons has been studied with the SELEX facility at Fermilab. Using the Primakoff formalism, we set a 90% CL upper limit on the radiative decay width Γ[Σ(1385)− → Σ−γ] < 9.5 keV, and estimate the cross section for γΣ− → Λπ− at √s ≈ 1.385GeV to be 56± 16μb.

A search for $CP$ violation in charmless three-body $\Xi_b^- \to p K^- K^-$ decays is performed using $pp$ collision data recorded with the LHCb detector, corresponding to integrated luminosities of $1\,\text{fb}^{-1}$ at a centre-of-mass energy $\sqrt{s} = 7\,\text{TeV}$, $2\,\text{fb}^{-1}$ 8\,\text{TeV}$ and 13\,\text{TeV}$. good description phase-space distribution obtained an amplitude mod...

Yields and spectra of Σ(1385) are measured in p+p, d+Au and Au+Au collisions at √ s NN =200 GeV. The nuclear modification factors in d + Au collisions are presented. The pT dependent medium effects are investigated via the nuclear modification factors. The implications of these results on various models are discussed.

This paper describes the LIA speaker recognition system developed for the Speaker Recognition Evaluation (SRE) campaign. Eight sub-systems are developed, all based on a state-of-the-art approach: i-vector/PLDA which represents the mainstream technique in text-independent speaker recognition. These sub-systems differ: on the acoustic feature extraction front-end (MFCC, PLP), at the i-vector extr...

Four experiments examined 3- and 4-year-olds' ability to communicate about containment and proximity relations. One hundred twenty-eight children either described where a miniature mouse was hiding in a dollhouse or they searched for the mouse after the experimenter described where it was hiding. The mouse was always hidden with a small landmark that was either in or next to a large landmark. W...

OBJECTIVE To study chronic pain not caused by somatic disease in adolescents and the effect of pain on the quality of life of the adolescents and their families. METHODS One hundred twenty-eight youngsters (12-18 years) who had reported chronic pain kept a 3-week diary of their pain and completed a questionnaire on quality of life. Their mothers completed a questionnaire on the impact of thei...
