Quantum Computing for High-Energy Physics: State of the Art and Challenges. Summary of the QC4HEP Working Group
Alberto Di Meglio, Karl Jansen, Ivano Tavernelli +43
Quantum computers offer an intriguing path for a paradigmatic change of computing in the natural sciences and beyond, with the potential for achieving a so-called quantum advantage…
High-Frequency Gravitational Wave Detection via Optical Frequency Modulation
Torsten Bringmann, Valerie Domcke, Elina Fuchs +1
High-frequency gravitational waves can be detected by observing the frequency modulation they impart on photons. We discuss fundamental limitations to this method related to the fa…
The Forward Physics Facility at the High-Luminosity LHC
Jonathan L. Feng, Felix Kling, Mary Hall Reno +233
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…
Constraining the CP structure of Higgs-fermion couplings with a global LHC fit, the electron EDM and baryogenesis
Henning Bahl, Elina Fuchs, Sven Heinemeyer +5
CP violation in the Higgs couplings to fermions is an intriguing, but not yet extensively explored possibility. We use inclusive and differential LHC Higgs boson measurements to fi…
Collider searches of scalar singlets across lifetimes
Elina Fuchs, Oleksii Matsedonskyi, Inbar Savoray +1
Spin-0 singlets arise in well-motivated extensions of the Standard Model. Their lifetime determines the best search strategies at hadron and lepton colliders. To cover a large rang…
Analytic Techniques for Solving the Transport Equations in Electroweak Baryogenesis
Elina Fuchs, Marta Losada, Yosef Nir +1
We develop an efficient method for solving transport equations, particularly in the context of electroweak baryogenesis. It provides fully-analytical results under mild approximati…

Cyrille Solaro, Steffen Meyer, Karin Fisher +3
We perform high-resolution spectroscopy of the dDdD interval in all stable even isotopes of Ca (A = 40, 42, 44, 46 and 48) with an accuracy…
violation from , and dimension-6 Yukawa couplings -- interplay of baryogenesis, EDM and Higgs physics
Elina Fuchs, Marta Losada, Yosef Nir +1
We explore the implications of the Standard Model effective field theory (SMEFT) with dimension-six terms involving the Higgs boson and third-generation fermion fields on the rate…
Implications of the upper bound on on the baryon asymmetry of the Universe
Elina Fuchs, Marta Losada, Yosef Nir +1
The upper bounds from the ATLAS and CMS experiments on the decay rate of the Higgs boson to two muons provide the strongest constraint on an imaginary part of the muon Yukawa coupl…
MSSM Higgs Boson Searches at the LHC: Benchmark Scenarios for Run 2 and Beyond
Emanuele Bagnaschi, Henning Bahl, Elina Fuchs +8
We propose six new benchmark scenarios for Higgs boson searches in the Minimal Supersymmetric Standard Model. Our calculations follow the recommendations of the LHC Higgs Cross Sec…
Relaxion and light (pseudo)scalars at the HL-LHC and lepton colliders
Claudia Frugiuele, Elina Fuchs, Gilad Perez +1
We study the potential of future lepton colliders, running at the Z-pole and above, and the High-Luminosity LHC to search for the relaxion and other light scalars . We investiga…
-violating effects on MSSM Higgs searches
Shruti Patel, Elina Fuchs, Stefan Liebler +1
We study the effects of -violating phases on the phenomenology of the Higgs sector of the MSSM. Complex parameters in the MSSM lead to -violating mixing…
Probing new spin-independent interactions through precision spectroscopy in atoms with few electrons
Cédric Delaunay, Claudia Frugiuele, Elina Fuchs +1
The very high precision of current measurements and theory predictions of spectral lines in few-electron atoms allows to efficiently probe the existence of exotic forces between el…
Interference effects in MSSM Higgs searches at the LHC
Elina Fuchs, Georg Weiglein
Complex parameters in the MSSM lead to mixing and interference between the two heavier neutral CP-even and CP-odd Higgs states. These effects can become very large in the case of a…

Elina Fuchs, Georg Weiglein
Interference and mixing effects between neutral Higgs bosons in the MSSM with complex parameters are shown to have a significant impact on the interpretation of LHC searches for ad…

Julian C. Berengut, Dmitry Budker, Cedric Delaunay +8
In this Letter we explore the potential of probing new light force-carriers, with spin-independent couplings to the electron and the neutron, using precision isotope shift spectros…
Breit-Wigner approximation for propagators of mixed unstable states
Elina Fuchs, Georg Weiglein
For systems of unstable particles that mix with each other, an approximation of the fully momentum-dependent propagator matrix is presented in terms of a sum of simple Breit-Wigner…
Phenomenology of relaxion-Higgs mixing
Thomas Flacke, Claudia Frugiuele, Elina Fuchs +2
We show that the relaxion generically stops its rolling at a point that breaks CP leading to relaxion-Higgs mixing. This opens the door to a variety of observational probes since t…
Constraining New Physics Models with Isotope Shift Spectroscopy
Claudia Frugiuele, Elina Fuchs, Gilad Perez +1
Isotope shifts of transition frequencies in atoms constrain generic long- and intermediate-range interactions. We focus on new physics scenarios that can be most strongly constrain…
Interference effects of neutral MSSM Higgs bosons with a generalised narrow-width approximation
Elina Fuchs
Mixing effects in the MSSM Higgs sector can give rise to a sizeable interference between the neutral Higgs bosons. On the other hand, factorising a more complicated process into pr…
Interference effects in BSM processes with a generalised narrow-width approximation
Elina Fuchs, Silja Thewes, Georg Weiglein
