Observation of triple J/$\psi$ meson production in proton-proton collisions at $\sqrt{s}$ = 13 TeV

A. Tumasyan, W. Adam, Janik Walter Andrejkovic, T. Bergauer et autres

Protons consist of three valence quarks, two up-quarks and one down-quark, held together by gluons and a sea of quark-antiquark pairs. Collectively, quarks and gluons are referred to as partons. In a proton-proton collision, typically only one parton of each proton undergoes …

Measurement of the differential cross section and charge asymmetry for inclusive pp $\mathrm{\to W^\pm + X}$ production at $\mathrm{\sqrt s = 8 TeV}$

Vardan Khachatryan, R. Erbacher, C. A. Carrillo Montoya, W. Carvalho et autres

The differential cross section and charge asymmetry for inclusive pp to W + X to mu-nu + X production at sqrt(s) = 8 TeV are measured as a function of muon pseudorapidity. The data sample corresponds to an integrated luminosity of 18.8 …

Measurement of the ratio $\mathcal{B}( B_s^0\rightarrow J/\psi f_0(980))/\mathcal{B}(B_s^0\rightarrow J/\psi\phi(1020))$ in pp collisions at $\sqrt{s} = 7~$TeV

Vardan Khachatryan, R. Erbacher, C. A. Carrillo Montoya, C. S. Moon et autres

The ratio $R_{\, \mathrm{f}_0 / \phi}$ of the branching fractions of the $\mathrm{B}^0_{s}$ meson to the CP-odd eigenstate $\mathrm{J}/\psi\, \mathrm{f}_0(980)$ and to $\mathrm{J}/\psi\, \phi(1020)$ is measured, where $\mathrm{J}/\psi \to \mu^+\mu^-$, $\mathrm{f}_0 \to \pi^+\pi^-$, and $\phi \to \mathrm{K}^+\mathrm{K}^-$. The analysis is based on …
