abstract
TikZ-Feynman is a LaTeX package allowing Feynman diagrams to be easily generated within LaTeX with minimal user instructions and without the need of external programs. It builds upon the TikZ package and leverages the graph placement algorithms from TikZ in order to automate the placement of many vertices. TikZ-Feynman still allows fine-tuned placement of vertices so that even complex diagrams can still be generated with ease.

Establishes the Topological Graviton Equivalence Theorem to prove large energy cancellations in N-point massive graviton amplitudes and constructs three- and four-point amplitudes via double copy from topologically massive Yang-Mills.
Kira 2.0 implements finite-field coefficient reconstruction for IBP reductions and improved user-equation handling, yielding lower memory use and faster performance on state-of-the-art problems.
Including mesonic fluctuations beyond mean field substantially modifies the phase structure of the quark-meson-diquark model, with diquark condensation dominating for strong couplings as analyzed via diquark pole mass and the Silver-Blaze property.
Within HQET, radiative semileptonic decay form factors for Lambda(b) to Lambda(c) and B to D(*) transitions are fully determined by non-radiative Isgur-Wise functions and heavy-hadron magnetic dipole moments in soft and sub-leading soft regions.
ALPs with LFV couplings above the muon mass threshold can be produced in LFV meson, tau, and gauge boson decays, yielding clean eμ signatures that enable new searches at future experiments.
One-loop corrections in the complex Higgs triplet model shift the 125 GeV Higgs decay rates to WW* and ZZ* upward by a few percent relative to the SM, while allowing up to -20% deviation in gamma gamma and 100% in the self-coupling.
At TeV lepton colliders the neutrino-associated Zh production cross section surpasses direct Zh production above a few TeV, with interference patterns made interpretable by the Feynman-diagram gauge.
