In the Institute of Physical and Chemical Research(RIKEN),using high intensity heavy ion beams from the R/KEN Linear Accelerator,productions and decays of isotopes of the heaviest elements have been investigated by using the gas-filled recoil separator,*** isotopes studied were Hs,Ds,Rg,112,and 113,*** on the observed decay chains consisting of consecutive alpha decays connected to the previously known alpha decays or spontaneous fissions,assignments of the initially produced isotopes were *** data with the atomic number from 108 to 112,agree well with the data previously *** production cross section of the isotope 113 of the 113th element have reached around 32 tl0 which shows the simple decrease of the cross section with the increase of the atomic number. The isotopes were produced,for the first time in the In evaporation channel from heavy-ion induced fusion reaction.

The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,plays an important role in various analyses performed at the Large Hadron Collider,as standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced *** paper describes the measurement of the efficiencies of quark/gluon taggers developed within the ATLAs Collaboration,using √s=13 TeV proton–proton collision data with an integrated luminosity of 140 fb^(-1) collected by the ATLAs *** taggers with high performances in rejecting jets from gluon over jets from quarks are studied:one tagger is based on requirements on the number of inner-detector tracks associated with the jet,and the other combines several jet substructure observables using a boosted decision tree.A method is established to determine the quark/gluon fraction in data,by using quark/gluon-enriched subsamples defined by the jet *** in tagging efficiency between data and simulation are provided for jets with transverse momentum between 500 GeV and 2 TeV and for multiple tagger working points.
