Model-independent energy budget for LISA / Giese, Felix ; Konstandin, Thomas ; Schmitz, Kai ; van de Vis, Jorinde
We provide an easy method to obtain the kinetic energy fraction in gravitational waves, generated during a cosmological first-order phase transition, as a function of only the wall velocity and quantities that can be determined from the particle physics model at the nucleation temperature. [...]

The Schwarzschild-Tangherlini metric from scattering amplitudes in various dimensions / Mougiakakos, Stavros ; Vanhove, Pierre
We derive the static Schwarzschild-Tangherlini metric by extracting the classical contributions from the multi-loop vertex functions of a graviton emitted from a massive scalar field. [...]

Pole skipping away from maximal chaos / Choi, Changha ; Mezei, Márk ; Sárosi, Gábor
Pole skipping is a recently discovered subtle effect in the thermal energy density retarded two point function at a special point in the complex $(\omega,p)$ planes. [...]

The Present and Future of Four Tops / Banelli, Giovanni ; Salvioni, Ennio ; Serra, Javi ; Theil, Tobias ; Weiler, Andreas
We study the phenomenology of a strongly-interacting top quark at future hadron and lepton colliders, showing that the characteristic four-top contact operators give rise to the most significant effects. [...]

Charting the Fifth Force Landscape / Banks, Hannah (Cambridge U., DAMTP) ; Mccullough, Matthew (CERN ; Cambridge U., DAMTP)
Fifth forces arising from hidden sector scalar operator exchange, as probed in a variety of present and planned experiments, can be captured by a general dispersion relation involving one real, positive, spectral density function. [...]
