We study effects of new physics beyond the Standard Model on SU(3) symmetry
in charmless hadronic two body B decays. It is found that several equalities
for some of the decay amplitudes, such as A(Bd(Bu)→π+π−,π+K−(π−Kˉ0))=A(Bs→K+π−,K−K+(K0Kˉ0)), A(Bd→π+ρ−,π−ρ+,K−ρ+,π+K∗−)=A(Bs→K+ρ−,π−K∗+,K−K∗+,K+K∗−), A(Bd(Bu)→ρ+ρ−,ρ+K∗−(ρ−Kˉ∗0))=A(Bs→K∗+ρ−,K∗−K∗+(K∗0Kˉ∗0)), predicted by SU(3) symmetry in the SM are not affected by new
physics. These relations provide important electroweak model independent tests
for SU(3) symmetry in B decays.Comment: 4 pages, revte
