Quark mass RG-running for $N_f$ =3 QCD in a $\chi SF$ setup / Plasencia, Isabel Campos ; Brida, Mattia Dalla ; de Divitiis, Giulia Maria ; Lytle, Andrew ; Papinutto, Mauro ; Pirelli, Ludovica ; Vladikas, Anastassios
We compute the nonperturbative quark mass RG-running in the range $\Lambda_{QCD}\lessapprox\mu\lessapprox M_W$ for $N_f=3$ massless QCD with a mixed action approach: sea quarks are regularised using nonperturbatively $O(a)$-improved Wilson fermions with Schrödinger functional (SF) boundary conditions, employing the configurations of 1802.05243, while valence quarks are regularised using nonperturbatively $O(a)$-improved Wilson fermions with chirally rotated Schrödinger functional boundary conditions ($\chi$SF).

General Analytical Conditions for Inflaton Fragmentation: Quick and Easy Tests for its Occurrence / Kim, Jinsu (CERN) ; McDonald, John (Lancaster U.)
Understanding the physics of inflaton condensate fragmentation in the early Universe is crucial as the existence of fragments in the form of non-topological solitons (oscillons or Q-balls) may potentially modify the evolution of the post-inflation Universe. [...]

Likelihood analysis of the flavour anomalies and $g-2$ in the general two Higgs doublet model / Athron, Peter (Nanjing Normal U. ; Monash U.) ; Balazs, Csaba ; Gonzalo, Tomás E. ; Jacob, Douglas ; Mahmoudi, Farvah ; Sierra, Cristian
We present a likelihood analysis of the general two Higgs doublet model, using the most important currently measured flavour observables, in view of the anomalies in charged current tree-level and neutral current one-loop rare decays of $B$ mesons in $b\to c l \overline{\nu}$ and $b\to s\mu^{+}\mu^{-}$ transitions, respectively.
