Using a constituent quark model we study the mass and decay channels of meson meson and meson baryon structures in the charm sector. We show that the $X(3872)$ and $X(3940)$ resonances can be described as mixed charmonium-molecular states with $J^{PC}=1^{++}$, whereas the $X(3915)$ and the $Y(3940)$ can be assigned to similar mixed states with $J^{PC}=0^{++}$. In the baryon spectrum we identify the $\Lambda^+_c(2940)$ as a $D^*N$ molecule with $(I)J^P=(0)3/2^-$ and the recently reported $X_c…

Search for lepton-flavor-violating tau-lepton decays to ‘γ at Belle The BELLE collaboration

: Charged lepton flavor violation is forbidden in the Standard Model but pos-sible in several new physics scenarios. In many of these models, the radiative decays τ ± → ‘ ± γ ( ‘ = e, µ ) are

The LHCb Collaboration

We measure the B0 − B0 mixing frequency ∆md using ∼ 6000 B0 → D−(K+π−π−)π+ candidates from 36 pb−1 of data taken in physics runs of the LHCb experiment in 2010. We use opposite and same side tagging
