There is broad agreement that the next major collider should include an e⁺e⁻ Higgs factory mode. Yet, given the remarkable progress expected from the HL-LHC, I argue that a program focusing too heavily on Higgs coupling measurements is not ambitious enough, be it linear or circular. The critical question is what additional capabilities each design offers. Circular machines provide unparalleled...

In this poster, I will analyze the potential signatures of a first-order electroweak phase transition in the early Universe. Since the Standard Model does not allow for such a transition, I will explore a simple extension of the scalar sector—the Two Higgs Doublet Model (2HDM)—which introduces a second Higgs doublet.
If the phase transition is strong enough, it proceeds via the spontaneous...

Simulating entire beamlines for future linear colliders remains a significant challenge due to the diversity of components and the wide range of physical effects that must be accurately modelled. This is particularly true for colliders based on advanced accelerator concepts such as plasma acceleration. The Adaptable Beginning-to-End Linac (ABEL) simulation framework employs a modular...

Plasma-wakefield acceleration holds great promise for particle physics due to its orders-of-magnitude higher accelerating gradients, which can result in significant cost reductions based on a sizeable reduction in footprint. However, plasma-based acceleration of positrons—required for an electron-positron collider—is much more difficult than for electrons. In 2023 a novel collider scheme,...

The coupling of the Higgs boson to first and second generation fermions has yet to be measured experimentally. There still could be very large deviations in these couplings, as the origin of flavor is completely unknown. Nevertheless, if Yukawa couplings are modified, especially for light generations, there are generically strong constraints from flavor-changing neutral currents (FCNCs). ...
