Conservative Black Hole Scattering at Fifth Post-Minkowskian and First Self-Force Order / Driesse, Mathias ; Jakobsen, Gustav Uhre ; Mogull, Gustav ; Plefka, Jan ; Benjamin Sauer ; Usovitsch, Johann
We compute the 5PM order contributions to the scattering angle and impulse of classical black hole scattering in the conservative sector at first self-force order (1SF) using the worldline quantum field theory formalism. [...]

NNLO QCD corrections to the $q^2$ spectrum of inclusive semileptonic $B$-meson decays / Fael, Matteo ; Herren, Florian
We calculate the next-to-next-to-leading order QCD corrections to the leptonic invariant mass ($q^2$) spectrum of semileptonic $b \to c$ inclusive decays, taking into account the mass of the charm quark and the charged lepton in the final state. [...]

Gravitational waves from first-order phase transitions in LISA: reconstruction pipeline and physics interpretation / Caprini, Chiara (Geneva U., Dept. Theor. Phys. ; CERN) ; Jinno, Ryusuke (Tokyo U., RESCEU) ; Lewicki, Marek (Warsaw U.) ; Madge, Eric (Weizmann Inst.) ; Merchand, Marco (Royal Inst.

Phys.) ; Vaskonen, Ville (INFN, Padua ; INFN, Italy ; Unlisted, EE)
We develop a tool for the analysis of stochastic gravitational wave backgrounds from cosmological first-order phase transitions with LISA: we initiate a template databank for these signals, prototype their searches, and forecast their reconstruction. [...]

Nonthermal Heavy Dark Matter from a First-Order Phase Transition / Giudice, Gian F. ; Lee, Hyun Min ; Pomarol, Alex ; Shakya, Bibhushan
We study nonthermal production of heavy dark matter from the dynamics of the background scalar field during a first-order phase transition, predominantly from bubble collisions. [...]

Bispectral duality and separation of variables from surface defect transition / Jeong, Saebyeok ; Lee, Norton
We study two types of surface observables $-$ the $\mathbf{Q}$-observables and the $\mathbf{H}$-observables $-$ of the 4d $\mathcal{N}=2$$A_1$-quiver $U(N)$ gauge theory obtained by coupling a 2d $\mathcal{N}=(2,2)$ gauged linear sigma model. [...]

Small instanton-induced flavor invariants and the axion potential / Bedi, Ravneet ; Gherghetta, Tony ; Grojean, Christophe ; Guedes, Guilherme ; Kley, Jonathan ; Vuong, Pham Ngoc Hoa
Small instantons which increase the axion mass due to an appropriate modification of QCD at a UV scale $\Lambda_{\rm SI}$, can also enhance the effect of CP-violating operators to shift the axion potential minimum by an amount, $\theta_{\rm ind}$, proportional to the flavorful couplings in the SMEFT.

Dark matter as the trigger of flavor changing neutral current decays of the top quark / Jueid, Adil ; Kanemura, Shinya
We suggest a simplified model that simultaneously addresses the dark-matter problem and give rise to top quark flavor changing neutral current (FCNC) interactions at the one-loop order. [...]

(IAS, Julich ; JCHP, Julich ; Unlisted, DE) ; Lee, Dean (Michigan State U.) et al.
Whether or not femto-scale droplets of quark-gluon plasma (QGP) are formed in so-called small systems at high-energy colliders is a pressing question in the phenomenology of the strong interaction. [...]

Axion Star Explosions and the Reionization History of the Universe / Escudero, Miguel (CERN)
Cosmological structure formation simulations of ultralight axion-like dark matter have shown that an axion star forms at the center of every dark matter halo in the Universe. [...]
