On the Charged and CP-violating Kink Solutions in the Two Higgs Doublet Model / Law, Kai Hong (Manchester U.) ; Pilaftsis, Apostolos (Manchester U. ; CERN)
Minimal extensions of the Standard Model (SM), such as the so-called Two Higgs Doublet Model (2HDM), can possess several accidental discrete symmetries whose spontaneous breakdown in the early universe usually lead to the formation of domain walls. [...]

$VH+\text{jet}$ production in hadron-hadron collisions up to order $\alpha_s^3$ in perturbative QCD / Gauld, R. (Nikhef, Amsterdam ; Zurich, ETH) ; Ridder, A. Gehrmann-De (Zurich U.) ; Glover, E.W.N. (Durham U., IPPP ; Durham U.) ; Huss, A. (CERN) ; Majer, I.
We present precise predictions for the hadronic production of an on-shell Higgs boson in association with a leptonically decaying gauge boson and a jet up to order $\alpha_s^3$. [...]

Measurements of heavy-flavor production as a function of multiplicity with ALICE at the LHC / Bailung, Yoshini (Utrecht U. ; Indian Inst. Tech., Indore)
In this contribution, the production of heavy-flavor hadrons as a function of multiplicity, via the study of the D-meson and heavy-flavor hadron decay leptons self-normalized yields in pp collisions at the center of mass energy $\sqrt{s} = 13$ TeV is discussed. [...]

Transverse spherocity dependence of azimuthal anisotropy in heavy-ion collisions at the LHC using a multi-phase transport model / Mallick, Neelkamal (Indian Inst. Tech., Indore) ; Sahoo, Raghunath (Indian Inst. Tech., Indore ; CERN) ; Tripathy, Sushanta (INFN, Bologna) ; Ortiz, Antonio (Mexico U., ICN)
One of the event shape observables, the transverse spherocity ($S_0$), has been studied successfully in small collision systems such as proton-proton collisions at the LHC as a tool to separate jetty and isotropic events. [...]
