We study transition form factors for decays of D mesons. That is, we consider matrix elements of the weak left-handed quark current for the transitions D → P and D → V, where P and, V are light pseudoscalar or vector mesons, respectively. Our motivation to perform the present study of these form factors is future calculations of nonleptonic decay amplitudes. We consider the transition form factors within a class of chiral quark models. Especially, we study how the large energy effective theory limit works for D-meson decays. In this paper, we extend previous work on the case B → π to the case D → P ¼ π, K. Further, we extend our previous model based on the large energy effective theory to the entirely new case D → V ¼ ρ; K Ã ; … To determine some of the parameters in our model, we use existing data and results based on some other methods like lattice calculations, light-cone sum rules, and heavy-light chiral perturbation theory. We also obtain some new predictions for relations between form factors.

“…In this paper, we will extend the LEχQM further to include energetic vector mesons, V μ n in analogy with M n in Eq. (50). In this model, we will use a derivative coupling, as was used for the coupling of light energetic mesons to quarks through an axial vector field in Eq.…”

I would like to thank my advisor Jan Olav Eeg for his guidance, patience and motivation during these years. I also thank the professors Farid Ould-Saada, Carsten Lutken and Are Raklev who were my teachers. Thanks also to my office mate Sergey and my fellow students Marianne, Marius and the members of the theory group for their support both technical and social. I would also like to thank my PhD committee. My children Thomas and Andreas and my husband Roar were patient with my late working hours, weekend work, and with some truncated vacations. Roar also helped with proof reading, providing useful writing advice, and did the usual house and family work when I was occupied with equations and calculations. I would also like to thank Bjørg and Asgeir who supported the project fully as well, which was also very important to me.
