Measurement of the radiative K-e3 branching ratio

2005

We present a measurement of the relative branching ratio of the decay KL -> pi e nu gamma (Ke3gamma) with respect to KL-> pi e nu (gamma) (Ke3+Ke3gamma) decay. The result is based on observation of 19 000 Ke3gamma and 5.6 x 10^6 Ke3 decays. The value of the branching ratio is Br(Ke3gamma, Egamma^*>30 MeV,theta(e,gamma)^*>20^o)/Br(Ke3)= (0.964+-0.008+0.011-0.009)%. This result agrees with theoretical predictions but is at variance with a recently published result.

Development and implementation of the AIDA International Registry for patients with Behçet's disease

2022

AbstractPurpose of the present paper is to point out the design, development and deployment of the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to pediatric and adult patients with Behçet’s disease (BD). The Registry is a clinical physician-driven non-population- and electronic-based instrument implemented for the retrospective and prospective collection of real-life data about demographics, clinical, therapeutic, laboratory, instrumental and socioeconomic information from BD patients; the Registry is based on the Research Electronic Data Capture (REDCap) tool, which is thought to collect standardised information for clinical real-life research, and has been rea…

A measurement of the K-S lifetime

2002

A measurement of the K_S lifetime is presented using data recorded by the NA48 experiment at the CERN-SPS during 1998 and 1999. The K_S lifetime is derived from the ratio of decay time distributions in simultaneous, collinear K_S and K_L beams, giving a result which is approximately independent of the detector acceptance and with reduced systematic errors. The result obtained is tau_S=(0.89598 +- 0.00048 +- 0.00051)x10^(-10) s, where the first error is statistical and the second systematic.

Search for the decay K-s -> pi(0)e(+)e(-)

2001

Abstract A search for the decay K S →π 0 e + e − has been made using the NA48 detector at the CERN SPS. Using data collected in 1999 during a 40-hour run with a high-intensity KS beam, an upper limit for the branching fraction B (K S →π 0 e + e − ) −7 at 90% confidence level has been obtained.

Safety profile of the interleukin-1 inhibitors anakinra and canakinumab in real life clinical practice: a nationwide multicenter retrospective observ…

2018

A few studies have reported the safety profile of interleukin (IL)-1 blockers from real life. The aim of this study is to describe anakinra (ANA) and canakinumab (CAN) safety profile in children and adults, based on data from a real-life setting. Demographic, clinical, and therapeutic data from patients treated with ANA and CAN were retrospectively collected and analyzed. Four hundred and seventy five patients were enrolled; ANA and CAN were prescribed in 421 and 105 treatment courses, respectively. During a mean follow-up of 24.39 ± 27.04 months, 89 adverse events (AE) were recorded; 13 (14.61%) were classified as serious AE (sAE). The overall estimated rate of AE and sAE was 8.4 per 100 p…

Kaon physics at the CERN-SPS

2015

The NA48/2 and NA62 collaborations report on recent results, current status, and prospects of kaon physics at the CERN-SPS. The NA62 collaborations aims to measure the decay [Formula: see text] with an uncertainty of 10% or better. The NA62 detector and preliminary results from a pilot run in 2014 are presented. In addition, recent results of the NA48/2 collaboration are reported. A search for Dark Photons has been performed in [Formula: see text] decays via the kaon decays [Formula: see text] and [Formula: see text]. No dark photon signal was observed and new upper limits on the mixing parameter [Formula: see text] and the dark photon mass were computed. We also report the first observati…
