In this article, two different systems subject to shocks occurring based on a non-homogeneous Poisson process (NHPP) are analyzed. Type –I system is consisted of a single unit and type –II system is consisted of two parallel units in which both units operate identically and simultaneously. In type –I system occurrence of a shock causes system stopping and consequently will be received minimal r...

We search for an axion-like particle (ALP) a through the process ψ(3686)→π+π−J/ψ, J/ψ→γa, a→γγ in data sample of (2.71±0.01)×109 ψ(3686) events collected by BESIII detector. No significant ALP signal is observed over expected background, and upper limits on branching fraction decay J/ψ→γa ALP-photon coupling constant gaγγ are set at 95% confidence level mass range 0.165≤ma≤2.84GeV/c2. The B(J/ψ...

Let G = (V;E) be a graph. A total labeling ψ : V ⋃ E → {1, 2, ....k} is called totally irregular k-labeling of if every two distinct vertices u and v in (G) satisfy wt(u) ≠wt(v); edges u1u2 v1v2 E(G) wt(u1u2) ≠ wt(v1v2); where (u) + ∑uv∊E(G) ψ(uv) ψ(u1) ψ(u1u2) ψ(u2): The minimum k for which graph has the irregularity strength G, denoted by ts(G): In this paper, we determine exact value cubic g...

Using a data sample collected with the BESIII detector operating at BEPCII storage ring, Born cross section of process e+e−→ηJ/ψ center-of-mass energy s=3.773 GeV is measured to be (8.88±0.87±0.42) pb. We fit line shape before correcting for initial state radiation from 4.600 obtain branching fraction B(ψ(3770)→ηJ/ψ). B(ψ(3770)→ηJ/ψ)=(11.3±5.9±1.1)×10−4 when ψ(3770) decay amplitude added cohere...

An analysis of the J/ψ→ηη′γ decay by BESIII collaboration claims observation an exotic state η1(1855) with IGJPC=0+1−+. To establish its C-parity partner η1′(1855) in picture KK¯1(1400) molecular state, we propose that J/ψ→η1′(1855)η(′) receives main contributions from final interaction KK⁎(K+K⁎−, K−K⁎+, K0K¯⁎0, and K¯0K⁎0). Specifically, K K⁎ J/ψ→KK⁎ decays transform as η1′(1855)η(′), exchangi...
