1. Top-Quark Mass Scheme Uncertainties in Higgs Boson Pair Production via Gluon Fusion hep-ph · 14 Oct · 4 hits

   We investigate theoretical uncertainties arising from the choice of the top-quark mass scheme in Higgs boson pair production via gluon fusion. First, we implement the resummation of the…

2. Strangeness suppression, the $\phi$ meson and $\Lambda\bar\Lambda$ spin correlations from exact strangeness conservation at the quark level hep-ph · 14 Oct · 5 hits

   …small collision systems strange hadrons are suppressed, and the suppression grows with the number of strange quarks. Exact strangeness conservation in a finite volume accounts for this, but when it is imposed on…

3. Excited-State Effects in Nucleon Sigma Terms from a Variational Analysis hep-lat · 14 Oct · 2 hits

   …three gauge ensembles, including one ensemble simulated with two degenerate light, a strange, and a charm quark with quark masses tuned to approximately their physical value. We solve the generalized eigenvalue…

4. Transport of hard probes in the glasma hep-ph · 14 Oct · 5 hits

   The quark-gluon plasma (QGP) formed in relativistic heavy-ion collisions at RHIC and the LHC thermalizes from an…

5. The dead-cone effect in charm, bottom and top quark jets in angular and momentum space hep-ph · 14 Oct · 9 hits

   The dead-cone effect reflects the mass dependence of QCD radiation from heavy quarks. We investigate this phenomenon from charm and bottom to top quarks using two-dimensional angular…

6. The Semileptonic B Frontier: LHC, B-factories, Lattice QCD & the Hunt for Precision hep-ph · 14 Oct · 1 hit

   …Belle~II, and LHCb with state-of-the-art theoretical inputs---including Lattice QCD determinations, Heavy Quark Expansion (HQE) frameworks, and QED radiative corrections. In addition to reviewing the status of CKM…

7. Strange-quark-number-dependent response to partonic dynamics in baryon-rich Au+Au collisions nucl-th · 14 Oct · 3 hits

   We identify a strange-quark-number-dependent hierarchy in the response to explicit partonic dynamics by comparing PHSD5.2 with its…
