Revealing domain wall stability during ultrafast demagnetization
Hung-Tzu Chang, Sergey Zayko, Timo Schmidt +5
The ultrafast control of nanoscale spin textures such as magnetic domain walls or skyrmions is essential for advancing high-speed, high-density spintronics. However, imaging their…
Refinements of the Bottom and Strange MSSM Higgs Yukawa Couplings at NNLO
Margherita Ghezzi, Seraina Glaus, Dario Müller +2
We extend the already existing two-loop calculation of the effective bottom-Yukawa coupling in the MSSM. In addition to the resummation of the dominant corrections for large values…
Controlling bubble and skyrmion lattice order and dynamics via stripe domain engineering in ferrimagnetic Fe/Gd multilayers
Tim Titze, Sabri Koraltan, Timo Schmidt +6
Ferrimagnetic Fe/Gd multilayers host maze-like stripe domains that transform into a disordered bubble/skyrmion lattice under out-of-plane magnetic fields at ambient temperature. Fe…
Vector Boson Scattering Processes: Status and Prospects
Diogo Buarque Franzosi, Michele Gallinaro, Richard Ruiz +26
Insight into the electroweak (EW) and Higgs sectors can be achieved through measurements of vector boson scattering (VBS) processes. The scattering of EW bosons are rare processes…
Full NLO predictions for vector-boson scattering into Z bosons and its irreducible background at the LHC
Ansgar Denner, Robert Franken, Mathieu Pellen +1
Vector-boson scattering into two Z bosons at the LHC is a key channel for the exploration of the electroweak sector of the Standard Model. It allows for the full reconstruction of…
Higgs Boson Production via Gluon Fusion: Soft-Gluon Resummation including Mass Effects
Timo Schmidt, Michael Spira
We analyze soft and collinear gluon resummation effects at the NLL level for Standard Model Higgs boson production via gluon fusion and the neutral scalar and pseudos…

We present the full next-to-leading-order electroweak and QCD corrections to vector-boson scattering into a pair of off-shell opposite-sign W bosons decaying into leptons of differ…
Mixed NNLO QCD x electroweak corrections of O(N_f α_s α) to single-W/Z production at the LHC
Stefan Dittmaier, Timo Schmidt, Jan Schwarz
First results on the radiative corrections of order O(N_fα_sα) are presented for the off-shell production of W or Z bosons at the LHC, where N_f is the number of fermion flavours…
All optical control of bubble and skyrmion breathing

The creation and control of magnetic spin textures is of great interest in fundamental research and future device-oriented applications. Fe/Gd multilayers host a rich variety of ma…
Dipolar-stabilized first and second-order antiskyrmions in ferrimagnetic multilayers
Michael Heigl, Sabri Koraltan, Marek VaÅatka +13
Skyrmions and antiskyrmions are topologically protected spin structures with opposite topological charge. Particularly in coexisting phases, these two types of magnetic quasi-parti…
