Article Synopsis
  • The study investigates CP symmetry violation in the decay of D^{+} particles into K^{-}K^{+}π^{+} using data from proton-proton collisions at a high energy of 13 TeV.
  • A unique model-independent method was employed to analyze the phase-space distributions of D^{+} and D^{-} particles, correcting for any instrumental biases using D_{s}^{+} decays.
  • The findings indicate no significant evidence of CP violation, with a p value of 8.1%, and measure specific CP asymmetry observables, marking this study as the most sensitive search of its kind in multibody decays.

The X-linked NONO gene encodes Non-Pou Domain-Containing Octamer-Binding Protein, a multifunctional member of the DBHS family involved in transcriptional regulation, RNA splicing and DNA repair. Pathogenic variants in NONO cause Intellectual Developmental Disorder, X-linked Syndromic (MIM #300967), characterised by intellectual disability, neurodevelopmental delay, cardiomyopathy, such as left ventricular non-compaction (LVNC), and congenital heart defects such as including atrial septal defect (ASD), ventricular septal defect (VSD), patent ductus arteriosus (PDA), and patent foramen ovale (PFO). This study reports three new patients with pathogenic hemizygous frameshift variants in NONO identified with exome sequencing, broadening the clinical presentation.

Objective: The aim of this study was to evaluate the different phases of the learning curve for robotic distal pancreatectomy (RDP) in international expert centers.

Summary Background Data: RDP is an emerging minimally invasive approach; however, only limited, mostly single center data are available on its safe implementation, including the learning curve.

Methods: Consecutive patients undergoing elective RDP from 16 expert centers across three continents were included to assess the learning curve.

Article Synopsis
  • A study was conducted on B^{+} decays to explore resonant structures using data from the LHCb experiment at various energy levels, totaling an integrated luminosity of 9 fb^{-1}.
  • The researchers performed a simultaneous amplitude fit on two decay channels, determining the C parities of resonances in the D^{*±}D^{∓} mass spectra.
  • Four new charmonium or charmoniumlike states were discovered, including η_{c}(3945) and h_{c}(4000), and the presence of T_{c[over ¯]s[over ¯]0}^{*}(2870)^{0} and T_{c[over ¯]s

A measurement of time-dependent CP violation in D^{0}→π^{+}π^{-}π^{0} decays using a pp collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7  fb^{-1}, is presented. The initial flavor of each D^{0} candidate is determined from the charge of the pion produced in the D^{*}(2010)^{+}→D^{0}π^{+} decay.
