Recent results on B-Physics and Quarkonia with the ATLAS detector
The paper describes several measurements recently completed by ATLAS: (a) the decay of $\Lambda^0_b$ into $\Lambda^0$ and $\psi(2\text{S})$, observed for the first time and compared to the decay into $\Lambda^0$ and $J/\psi$; (b) the decay of $B^0_c$ into $J/\psi D^+_s$ and $J/\psi D^{*+}_s$, includ...

description | The paper describes several measurements recently completed by ATLAS: (a) the decay of $\Lambda^0_b$ into $\Lambda^0$ and $\psi(2\text{S})$, observed for the first time and compared to the decay into $\Lambda^0$ and $J/\psi$; (b) the decay of $B^0_c$ into $J/\psi D^+_s$ and $J/\psi D^{*+}_s$, including polarisation measurement for the latter channel; (c) the measurement of the ratio of the $b$-quark fragmentation fractions $f_s/f_d$, which complements a previous measurement of LHCb over a different range of $p_{\text{T}}$ and $y$; (d) $B^+$ mass reconstruction in the decay of $B^+$ to $J/\psi$ and $K^+$ at ATLAS at 13 TeV $pp$ collisions; (e) measurement of the differential non-prompt $J/\psi$ production fraction at 13 TeV. |
