Measurement of the 232Th(n,f) cross section in the 1–200 MeV range at the CSNS Back-n
The 232Th(n,f) cross section is very important in basic nuclear physics and applications based on the Th/U fuel cycle. Using the time-of-flight method and a multi-cell fast-fission ionization chamber, a novel mea...

Discovery of oscillations above 200 keV in a black hole X-ray binary with Insight-HXMT
Low-frequency quasiperiodic oscillations (LFQPOs) are commonly found in black hole X-ray binaries, and their origin is still under debate. The properties of LFQPOs at high energies (above 30 keV) are closely r...

Open AccessExtraction and validation of a new set of CMS pythia8 tunes from underlying-event measurements
New sets of CMS underlying-event parameters (“tunes”) are presented for the pythia8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or ne...

Implications on the origin of cosmic rays in light of 10 TV spectral softenings
Precise measurements of the energy spectra of cosmic rays (CRs) show various kinds of features deviating from single power-laws, which give very interesting and important implications on their origin and propa...
