Determination of $$\mathcal{C}\mathcal{P}$$ C P -violating HZZ interaction with polarised beams at the ILC
Published 2025-01-01“…Abstract We study possible $${\mathcal{C}\mathcal{P}}$$ C P -violation effects of the 125 GeV Higgs to Z boson coupling at the 250 GeV ILC with transverse and longitudinal beam polarisation via the process $$e^+ e^- \rightarrow HZ \rightarrow H \mu ^-\mu ^+$$ e + e - → H Z → H μ - μ + . …”

Searching for string bosenovas with gravitational wave detectors
Published 2025-01-01“…In this paper, we study the subsequent evolution of this dense string network, and the resulting observational consequences depending on the unknown string tension, or almost equivalently, the ratio between the quartic and the gauge coupling in the Abelian Higgs model. Strings with large tension will dissipate into gravitational waves, detectable over a wide range of frequencies, from ~ nHz near supermassive blackholes, to ≳ 10MHz around stellar mass black holes. …”

FPF@FCC: neutrino, QCD, and BSM physics opportunities with far-forward experiments at a 100 TeV Proton Collider
Published 2025-01-01“…We fingerprint the BSM sensitivity of the FPF@FCC for a variety of models, including dark Higgs bosons, relaxion-type scenarios, quirks, and millicharged particles, finding that these experiments would be able to discover LLPs with masses as large as 50 GeV and couplings as small as 10 −8, and quirks with masses up to 10 TeV. …”
