A search for lepton-flavor-violating decays of the $Z$ boson into a $\tau$-lepton and a light lepton with the ATLAS detector
Direct searches for lepton flavor violation in decays of the $Z$ boson with the ATLAS detector at the LHC are presented. [...]

The Infrared Structure of Nambu-Goldstone Bosons / Low, Ian ; Yin, Zhewei
The construction of effective actions for Nambu-Goldstone bosons, and the nonlinear sigma model, usually requires a target coset space $G/H$. [...]

Measurement of D$^0$, D$^+$, D$^{*+}$ and D$^+_{\rm s}$ production in Pb-Pb collisions at $\mathbf{\sqrt{s_{\rm NN}}}= 5.02$ TeV / ALICE Collaboration
We report measurements of the production of prompt D$^0$, D$^+$, D$^{*+}$ and D$^+_{\rm s}$ mesons in Pb-Pb collisions at the centre-of-mass energy per nucleon-nucleon pair $\sqrt{s_{\rm NN}}=5.02$ TeV, in the centrality classes 0-10%, 30-50% and 60-80%. [...]

$\phi$ meson production at forward rapidity in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=2.76$ TeV / ALICE Collaboration
$\phi$ meson measurements provide insight into strangeness production, which is one of the key observables for the hot medium formed in high-energy heavy-ion collisions. [...]

Single-top associated production with a $Z$ or $H$ boson at the LHC: the SMEFT interpretation / Degrande, Celine ; Maltoni, Fabio ; Mimasu, Ken ; Vryonidou, Eleni ; Zhang, Cen
At the LHC, top quarks can be produced singly with a sizeable rate via electroweak interactions. [...]

NNLOPS accurate associated HZ production with NLO decay ${\rm{H}} \to b\bar{b}$ / Astill, William ; Bizon, Wojciech ; Re, Emanuele ; Zanderighi, Giulia
We present a next-to-next-to-leading order (NNLO) accurate description of associated HZ production, followed by the Higgs boson decay into a pair of $b$-quarks treated at next-to-leading order (NLO), consistently matched to a parton shower (PS). [...]

Boosted Dark Matter Quarrying at Surface Neutrino Detectors / Kim, Doojin ; Kong, Kyoungchul ; Park, Jong-Chul ; Shin, Seodong
We propose the idea of "Earth Shielding" to reject cosmic-ray backgrounds, in the search for boosted dark matter at surface neutrino detectors, resulting in the enhancement of the signal-to-background ratio. [...]

Bottom-quark effects in Higgs production at intermediate transverse momentum / Caola, Fabrizio ; Lindert, Jonas M. ; Melnikov, Kirill ; Monni, Pier Francesco ; Tancredi, Lorenzo ; Wever, Christopher
We provide a precise description of the Higgs boson transverse momentum distribution including top and bottom quark contributions, that is valid for transverse momenta in the range mb < pt < mt, where mb and mt are the bottom and top quark masses. [...]
