dc.description.abstractThe four decay modes D-0 -> phi pi(0), D-0 -> phi eta, D+ -> phi pi(+), and D+ up arrow phi K+ are studied by using a data sample taken at the centre-of-mass energy root s = 3.773 GeVwith the BESIII detector, corresponding to an integrated luminosity of 2.93 fb(-1). The branching fractions of the first three decay modes are measured to be B(D-0 -> phi pi(0)) = (1.168 +/- 0.028 +/- 0.028) x 10(-3), B(D-0 -> phi eta) = (1.81 +/- 0.46 +/- 0.06) x 10(-4), and B(D+ -> phi pi(+)) = (5.70 +/- 0.05 +/- 0.13) x 10(-3), respectively, where the first uncertainties are statistical and the second are systematic. In addition, the upper limit of the branching fraction for D+ -> phi K+ is given to be 2.1 x 10(-5) at the 90% confidence level. The ratio of B(D-0 -> phi pi(0)) to B(D+ -> phi pi(+)) is calculated to be (20.49 +/- 0.50 +/- 0.45)%, which is consistent with the theoretical prediction based on isospin symmetry between these two decay modes.
