    Review of bottomonium measurements from CMS

    Full text link
    We review the results on the bottomonium system from the CMS experiment at the Large Hadron Collider. Measurements have been carried out at different center-of-mass energies in proton collisions and in collisions involving heavy ions. These include precision measurements of cross sections and polarizations, shedding light on hadroproduction mechanisms, and the observation of quarkonium sequential suppression, a notable indication of quark-gluon plasma formation. The observation of the production of bottomonium pairs is also reported along with searches for new states. We close with a brief outlook of the future physics program.Comment: 32 page

    Effect of K0Kˉ0K^{0}-\bar{K}^{0} Mixing on CPCP Asymmetries in Weak Decays of DD and BB Mesons

    Full text link
    Within the standard electroweak model we carry out an instructive analysis of the effect of K0Kˉ0K^{0}-\bar{K}^{0} mixing on CPCP asymmetries in some weak decay modes of D±D^{\pm} and B()\stackrel{(-)}{B}d0^{0}_{d} mesons. We point out that a clean signal of CPCP violation with magnitude of 2Re(ϵ\epsilon) 3.3×103\approx 3.3\times 10^{-3} can manifest in the semileptonic decays D+l+νl KSD^{+}\rightarrow l^{+}\nu^{~}_{l}K_{S} (KLK_{L}) vs Dlνˉl KSD^{-}\rightarrow l^{-}\bar{\nu}^{~}_{l}K_{S} (KLK_{L}). The CPCP asymmetries are also dominated by 2Re(ϵ\epsilon) in the two-body nonleptonic decays D±(π±,ρ±,a1±)+(KS,KL)D^{\pm} \rightarrow (\pi^{\pm}, \rho^{\pm}, a^{\pm}_{1})+ (K_{S}, K_{L}) and in the multi-body processes D±π±+n0π0+n±(π±π)+(KS,KL)D^{\pm}\rightarrow \pi^{\pm}+n_{0}\pi^{0}+n_{\pm} (\pi^{\pm}\pi^{\mp})+ (K_{S}, K_{L}), where n0n_{0} and n±n_{\pm} are integers. It is possible to observe such CPCP-violating signals with about 10710^{7} D±D^{\pm} events at τ\tau-charm factories or hadron machines. Finally we show that the CPCP asymmetry induced by Re(ϵ\epsilon) may compete with those from Bd0Bˉd0B^{0}_{d}-\bar{B}^{0}_{d} mixing and final-state interactions in the semi-inclusive and exclusive decays BdX(ccˉ)+(KS,KL)B_{d}\rightarrow X(c\bar{c})+(K_{S}, K_{L}) on the Υ(4S)\Upsilon (4S) resonance.Comment: 10 Latex pages + 2 figures.
