 Top quark mass and cross sections in ATLAS and CMS / Defranchis, Matteo M. With the large data set delivered during the second run of the CERN LHC, inclusive and differential measurements of the top quark-antiquark production cross section at the ATLAS and CMS experiments often reach a precision that is comparable or superior to that of the corresponding theoretical calculations.

 Measurement of the production cross section of prompt $\Xi^0_{\rm c}$ baryons at midrapidity in pp collisions at $\sqrt{s}$ = 5.02 TeV / ALICE Collaboration The transverse momentum ($p_{\rm T}$) differential cross section of the charm-strange baryon $\Xi^0_{\rm c}$ is measured at midrapidity ($|y|<$ 0.5) via its semileptonic decay into ${\rm e^{+}}\Xi^{-}\nu_{\rm e}$ in pp collisions at $\sqrt{s}$ = 5.02 TeV with the ALICE detector at the LHC.

 The Amplitude for Classical Gravitational Scattering at Third Post-Minkowskian Order / Bjerrum-Bohr, N.E.J. (Bohr Inst.) ; Damgaard, P.H. (Bohr Inst. ; CERN) ; Planté, L. (Poincare Inst.) ; Vanhove, P. (IPhT, Saclay ; Higher Sch. of Economics, Moscow ; CERN) We compute the scattering amplitude for classical black-hole scattering to third order in the Post-Minkowskian expansion, keeping all terms needed to derive the scattering angle to that order from the eikonal formalism.

 Complete Set of Feynman Rules for Scalar Leptoquarks / Crivellin, Andreas (CERN ; Zurich U. ; PSI, Villigen) ; Schnell, Luc (Paris, LPTHE ; Zurich, ETH ; Ec. Polytech., Palaiseau (main)) Leptoquarks (LQs) have attracted increasing attention within recent years, mainly since they can explain the flavor anomalies found in $R(D^{(*)})$, $b \rightarrow s \ell^+ \ell^-$ transitions and the anomalous magnetic moment of the muon.
