Amplitude analysis of $B^0 \rightarrow \overline{D}^0 D_s^+ \pi^-$ and $B^+ \rightarrow D^- D_s^+ \pi^+$ decays
Resonant contributions in $B^0 \rightarrow \overline{D}{}^0 D^+_s\pi^-$ and $B^+\rightarrow D^- D^+_s\pi^+$ decays are determined with an amplitude analysis, which is performed both separately and simultaneously, where in the latter case isospin symmetry between the decays is assumed [...]

First observation of a doubly charged tetraquark and its neutral partner
A combined amplitude analysis is performed for the decays $B^0 \rightarrow \overline{D}{}^0 D^+_s\pi^-$ and $B^+\rightarrow D^- D^+_s\pi^+$, which are related by isospin symmetry. [...]

A truly cylindrical inner tracker for ALICE / Yüncü, Alperen
After the successful installation and first operation of the upgraded Inner Tracking System (ITS2), which consists of about $10\,$m$^2$ of monolithic silicon pixel sensors, ALICE is pioneering the usage of bent, wafer-scale pixel sensors for the ITS3 for LHC Run 4. [...]

Antipodal Self-Duality for a Four-Particle Form Factor / Dixon, Lance J. (SLAC) ; Gürdoğan, Ömer ; Liu, Yu-Ting ; McLeod, Andrew J. (CERN ; UCLA) ; Wilhelm, Matthias (Bohr Inst.)
We bootstrap the symbol of the maximal-helicity-violating four-particle form factor for the chiral part of the stress-tensor supermultiplet in planar $\mathcal{N}=4$ super-Yang-Mills theory at two loops. [...]

Measurement of the dependence of the hadron production fraction ratio $ f_\mathrm{s}/f_\mathrm{u} $ on B meson kinematic variables in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
The dependence of the ratio between the $ \mathrm{B}_{\mathrm{s}}^{0} $ and $ {\mathrm{B}^{+}} $ hadron production fractions, $ f_\mathrm{s}/f_\mathrm{u} $, on the transverse momentum ($ p_{\mathrm{T}} $) and rapidity of the B mesons is studied using the decay channels $ \mathrm{B}_{\mathrm{s}}^{0} \! \to \! \mathrm{J}/\psi \, \phi $ and $ {\mathrm{B}^{+}} \! \to \! \mathrm{J}/\psi \, \mathrm{K}^{+} $.
