Time-integrated and time-dependent measurements of CP violation are important to test the Standard Model (SM) description. In particular, the tree-level determination of the CKM angle gamma is a standard candle measurement of CP violation in the SM. The latest CP violation measurements using beauty to open charm decays from LHCb are presented.
The Belle II experiment collected a 19.2 fb$^{-1}$ sample of data at centre-of-mass energies near the $\Upsilon(10753)$ resonance. We present several results related to the following processes: $e^+e-\to \Upsilon(nS)\eta$, $e^+e-\to \gamma X_b(\chi_{bJ}\pi^+\pi^-)$, and $e^{+}e^{-}\to\chi_{bJ}(1P) \gamma$. These results provide additional information about the nature of the $\Upsilon(10753)$...
The Belle and Belle II experiments have collected a $1.6~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at centre-of-mass energies near the $\Upsilon(nS)$ resonances. We present a measurement of the $B^{0}$ and $B^+$ meson mass difference and a measurement of $\sigma\left(e^+ e^-\to J/\psi p\bar{p}\right)$ over a range of centre-of-mass energies accessed via initial-state radiation.
Recent CMS results on production of heavy hadrons is presented, including the measurement of total charm cross section in pp collisions at 7 TeV and the observation of simultaneous production of Y(1S) meson and Z boson in pp collisions at 13 TeV.
This talk will present recent results from the ATLAS experiment on measurements of the production of charmonium states and studies of heavy-flavour states spectroscopy, including that of exotic quarkonium.
Motivated by the recent observations of $T^*_{cs0}(2870)^0$, $T^*_{c\bar s 0}(2900)^0$ and $T^*_{c\bar s 0}(2900)^{++}$ charmed tetraquark states by LHCb, we study the decays of heavy mesons to these charmed tetraquark states ($T$) using a topological amplitude approach. We first obtain the $T\to DP$ and $DS$ strong decay amplitudes by decomposed them into several topological amplitudes, where...
