The BESIII experiment has collected the $e^+e^-$ collision data samples corresponding to integrated luminosities of 2.93 $mathrm{fb}^{-1}$, $3.19$ $mathrm{fb}^{-1}$, 3.13 $mathrm{fb}^{-1}$ and 567 $mathrm{pb}^{-1}$ at center-of-mass energies of 3.773 GeV, 4.178 GeV, 4.189-4.226 GeV and 4.599 GeV, respectively. We report the measurements of strong-phase parameters based on the decays $D^0to K^0_{S/L}pi^+pi^-$, $D^0to K^0_{S/L}K^+K^-$, $D^0to K^-pi^+pi^+pi^-$ and $D^0to K^-pi^+pi^0$, which are important input for binned model-independent measurement of the CKM angle $gamma/phi_3$. In addition, we report amplitude analyses and branching fraction measurements of $D^+$, $D_s^+$ and $Lambda_c^+$ decays along with the $Lambda_c^+$ spin determination.

Rare hadronic B-meson decays allow us to study CP violation. The class of B decays final states containing two vector mesons provides a rich set of angular correlation observables to study. This article reviews some of the recent experimental results from the BaBar and Belle collaborations.
We report about the studies of the decay channels B- -> D0 K-, B0 -> D*- a1+ and B0 -> Ds(*)- pi+ with a sample of 62.10^6 Upsilon(4S) decays into B meson pairs collected with the BaBar detector at the PEP II asymmetric e+ e- collider.
There has been important experimental progress in the sector of heavy baryons in the past several years. We study the strong decays of the S-wave, P-wave, D-wave and radially excited charmed baryons using the $^3P_0$ model. After comparing the calcul
ated decay pattern and total width with the available data, we discuss the possible internal structure and quantum numbers of those charmed baryons observed recently.
Rare B hadron decays provide an excellent test bench for the Standard Model and can probe new physics models. We review the experimental progress of the searches for rare leptonic B decays ($brightarrow ell^+ ell^-$ and $brightarrow s ell^+ ell^-$) at LHC and Tevatron experiments.
The CDF experiment at the Tevatron $pbar{p}$ collider established that extensive and detailed exploration of the $b$--quark dynamics is possible in hadron collisions, with results competitive and supplementary to those from $e^+e^-$ colliders. This provides a rich, and highly rewarding program that has currently reached full maturity. In the following I report some recent results on hadronic decays: the evidence for the charmless annihilation decay mode $B^0_s to pi^+pi^-$, and the first reconstruction in hadron collisions of the suppressed decays $B^- to D(to K^+pi^-)K^-$ and $B^- to D(to K^+pi^-)pi^-$.
