New physics coupled to the Higgs boson may hide it in the standard decay channels to be investigated at LHC. We consider the models where new invisible dominant decay modes of the Higgs boson are responsible for this hiding. We propose to study at LH

The status of exclusive two-body and three-body baryonic B decays is reviewed. The threshold enhancement effect in the dibaryon invariant mass and the angular distributions in the dibaryon rest frame are stressed and explained. Weak radiative baryoni

The pentaquark state of $\Theta^{+}(uudd\bar{s})$ has been observed to decay with two decay modes: $\Theta^+\to n K^+$ and $\Theta^+ \to p K^0$. The decay probability ratio of the two decay modes is studied with general symmetry consideration of isos

We report the preliminary measurement by the FOCUS Collaboration (E831 at Fermilab) of masses and widths of the L=1 charm mesons $D_2^{*0}$ and $D_2^{*+}$. The fit of the invariant mass distribution requires an additional term to account for a broad

Measurement results of photoproduced excited hyperon states using the CLAS detector at Jefferson Lab are shown. The invariant mass distribution of the Lambda(1405) has recently been shown to be different for each of the three Sigma pi channels that i

Observation of the $X(1840)$ in the $3(\pi^+\pi^-)$ invariant mass in $J/\psi\rightarrow\gamma 3(\pi^+\pi^-)$ at BESIII is reviewed. With a sample of $225.3\times10^6$ $J/\psi$ events collected with the BESIII detector at BEPCII, the $X(1840)$ is obs
