First measurement of the CKM angle ϕ3 with B±→ D($$ {K}_{\mathrm{S}}^0 $$π+π−π0) K± decays
A bstract We present the first model-independent measurement of the CKM unitarity triangle angle ϕ 3 using B ± → D ( $$ {K}_{\mathrm{S}}^0 $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mi>K</mml:mi> <mml:mi>S</mml:mi> <mml:mn>0</mml:mn> </mml:msubsup> </mml:math> π + π − π 0 ) K ± decays, where D indicates either a D 0 …
