Amplitude analysis ofB−→D+π−π−

Abstract

The Dalitz plot analysis technique is used to study the resonant substructures of B − → D þ π − π − decays in a data sample corresponding to 3.0 fb

Excited heavy meson decays to light vector mesons: Implications for spectroscopy

“…11. For D * 2 (3000) belonging to this doublet we predict The LHCb assignment for this particle is J P = 2 + [7], and mass and width are compatible with D * 0 J (3000) [6] (Tables II and III). It could be identified with the lowest lying J P = 2 + n = 2 stateD * 2 inT doublet, or with D * 2 belonging to the n = 1 F doublet.…”

“…The parameters of the J P = 3 − resonance are in Table IV. LHCb observed another candidate for the X doublet, D * 0 3 (2760) with parameters in Table III, that can be identified with the non-strange partner of D * − s3 (2860) [7]. Finally, BaBar and LHCb found a resonance that might be the J P = 2 − state in the X doublet: this is D 0 (2750) decaying to D * + π − [5], with parameters in Table I.…”

Bottom strange molecules with isospin 0

“…The third state predicted, Dð2600Þ, was found later in Ref. [10] and has been reconfirmed [11,12]. This work was extended to the case of the ρðωÞB Ã ðBÞ interaction in Ref.…”

Another Walk through the World of Chiral Dynamics

“…This can be done at LHCb and Belle-II. One expects to see nontrivial cusp structures at Figure 4: Fit to the LHCb data for the angular moments P 0 , P 1 − 14 P 3 /9 and P 2 for the B − → D + π − π − reaction [38]. The largest error among P 1 and 14 P 3 /9 in each bin is taken as the error of P 1 − 14 P 3 /9.…”
