A Collider for the 750 GeV Resonant State
Recent data collected by ATLAS and CMS at 13 TeV collision energy of the LHC
indicate the existence of a new resonant state with a mass of 750 GeV
decaying into two photons . The properties of should be
studied further at the LHC and also future colliders. Since only decay channel has been measured, one of the best ways to extract
more information about is to use a collider to produce
at the resonant energy. In this work we show how a
collider helps to verify the existence of and to provide some of the
most important information about the properties of , such as branching
fractions of . Here can be , , or . We
also show that by studying angular distributions of the final 's in
, one can obtain crucial information
about whether this state is a spin-0 or a spin-2 state.Comment: ReTex, 12 page with 6 figures. Expanded discussion on distinguishing

A high selective fluorescent sensor for Ni(II) ion in acetonitrile
In this paper, a high selective fluorescent sensor for nickel ion based on boron-dipyrromethene (BODIPY) has been studied. Upon addition of Ni(II) ion, the fluorescence of sensor (compound 1) would be quenched, and the selectivity towards Ni(II) ion over Ag(I), Cd(II), Cu(II), Fe(III), Hg(II), Pb(II), and Zn(II)is good in acetonitrile, there is almost no interference from other heavy metal ions. The stoichiometry of complexation for compound 1 with Ni(II) ion is 1:1, and the quenching process could be reversed by triethanolamine
