Resonant scattering in two-flavored Sp(4) lattice gauge theories
Ed Bennett, Yannick Dengler, Deog Ki Hong +8
We apply Lüscher's method to the vector channel of the scattering amplitude of Pseudo-Nambu-Goldstone-Bosons (PNGBs), in the lattice gauge theory coupled to flavors…
Vector-channel scattering of dark particles in a Sp(4) gauge theory
Jong-Wan Lee, Ed Bennett, Yannick Dengler +8
We report new results obtained in our lattice studies of the gauge theory coupled to two fundamental Dirac fermions. This theory provides a candidate for the dynamical orig…
Scattering of SIMPlectic Dark Pions
Yannick Dengler, Axel Maas, Fabian Zierler
We study the scattering of two identical pNGBs (pseudo-Nambu-Goldstone Bosons) in Sp(4) gauge theory with two mass-degenerate Dirac fermions in the pseudo-real fundamental represen…
Scattering of dark pions in Sp(4) gauge theory
Yannick Dengler, Axel Maas, Fabian Zierler
Analyzes of astrophysical data provide first hints on the self-interactions of dark matter at low energies. Lattice calculations of dark matter theories can be used to investigate…
Scattering of dark pions in an Sp(4) gauge theory
Yannick Dengler, Axel Maas, Fabian Zierler
In this work we consider strongly interacting dark matter candidates as composite states of fermions charged under a dark gauge group in the fundamental representat…
