Using.e^(+)e^(−)annihilation data corresponding.to an integ.ated luminosity.of 2.93 fb^(−1)taken at the center-of-mass energ.0}s=3.773 g.V with the bEsIII detector,a joint amplitude analy.is is performed on the decay. D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η).The fit fractions of individual components are obtained,and larg. interferences among.the dominant components of the decay. D^(0)→a_(1)(1260)π,D^(0)→π(1300)π,D^(0)→ρ(770)ρ(770),and D^(0)→2(ππ)_(s)are observed in both *** the obtained amplitude model,the CP-even fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are determined to be(75.2±1.1_(stat).±1.5_(sy.t.))%and(68.9±1.5_(stat).±2.4_(sy.t.))%,*** branching.fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are measured to be(0.688±0.010_(stat.)±0.010_(sy.t.))%and(0.951±0.025_(stat.)±0.021_(sy.t.))%,*** amplitude analy.is provides an important model for the binning.strateg.0}in measuring.the strong.phase parameters of D^(0)→4πwhen used to determine the CKM ang.eγ(ϕ_(3))via the b^(−)→DK^(−)decay.

Purpose The main scientific g.al of LHAAsO-wCDA is to survey.g.mma-ray.sources with energ.0}from 100 g.V to 30 *** observe hig.-energ.0}shower events,especially.to measure the energ.0}spectrum of cosmic ray. from 100 TeV to 10 PeV,a dy.amic rang. extension sy.tem(wCDA++)is desig.ed to use a 1.5-inch PMT with a dy.amic rang. of four orders of mag.itude for each cell in *** The dy.amic rang. is extended by.using.these PMTs to measure the effective charg. density.in the core reg.on of air shower events,which is an important parameter for identify.ng.the composition of primary.*** and Conclusion The sy.tem has been running.for more than one *** this paper,the details of the desig. and performance of wCDA++are presented.
