Many theories beyond the Standard Model (BSM) have been proposed to address several of the Standard Model shortcomings, such as the origin of dark matter and neutrino masses, the fine-tuning of the Higgs Boson mass, or the observed pattern of masses and mixing angles in the quark and lepton sectors. Many of these BSM extensions predict new particles or interactions directly accessible at the...

The proposed LUXE experiment (LASER Und XFEL Experiment) at DESY, Hamburg, using the 16.5 GeV electron beam from the European XFEL, aims to probe QED in the non-perturbative regime created in collisions between high-intensity laser pulses and high-energy electron or photon beams. In this strong-field regime, where the electromagnetic field of the laser is above the Schwinger limit, physical...

Neutrinos are the most elusive particles known. Heavier sterile neutrinos mixing with the Standard Model partners might solve the mystery of the baryon asymmetry of the universe and take part in the mass generation mechanism for the light neutrinos. From this perspective, if the heavy neutrinos are detected, it is crucial to determine their coupling structure. Future lepton colliders would not...

Intriguing scenarios of new physics provide explanation to several shortcomings of the Standard Model. Such models as extra dimensions, supersymmetric theories or dark sector extensions, are expected to manifest in various topologies including hadronic and leptonic final states.

In the Standard Model, the ground state of the Higgs field is not found at zero but instead corresponds to one of the degenerate solutions minimising the Higgs potential. In turn, this spontaneous electroweak symmetry breaking provides a mechanism for the mass generation of nearly all fundamental particles. The Standard Model makes a definite prediction for the Higgs boson self-coupling and...

23. Probing CPV mixing in the Higgs sector at an e+e- collider at around 1 TeV center-of-mass energyMrs Natasa Vukasinovic (VINCA Institute of Nuclear Sciences, Uni. Belgrade)16/05/2023, 13:50Track 1: Physics at e+e- collidersOral
Abstract: Although the studies of tensor structure of the Higgs boson interactions with vector bosons and fermions at CMS and ATLAS experiments have established that the JPC quantum numbers of the Higgs boson should be 0++, small CP violation in the Higgs sector (i.e. app. 10% contribution of the CP-odd state) cannot be excluded with the current experimental precision. We review possibilities...

The Higgs sector of particle physics is still largely uncovered, where establishing the Higgs mechanism is central to advance the field. The Higgs self-coupling is the key ingredient missing and an important puzzle piece for potentially uncovering new physics beyond the standard model.

The majority of Monte-Carlo (MC) simulation campaigns for future $e^+e^-$ colliders has so far been based on the leading-order (LO) matrix elements provided by Whizard 1.95, followed by parton shower and hadronization in Pythia6, using the tune of the OPAL experiment at LEP. In this contribution, we test and develop the interface between Whizard3 and Pythia8. As a first step, we simulate the...

The proposed physics programs at future lepton colliders will deliver a level of experimental precision that is unseen in our field. To ensure a successful physics program, significant improvements are needed in theoretical calculations to reach or surpass the experimental accuracy. One such theoretical avenue that can be improved is the treatment of electroweak radiative corrections in...

I give a short summary on scenarios with new physics scalars that could be investigated at future e+e− colliders. I concentrate on cases where at least one of the additional scalar has a mass below 125 GeV, and discuss both models where this could be realized, as well as studies which focus on such scenarios.

New sources of neutral scalar-mediated CP violation that arise in extended Higgs sectors can originate in the Yukawa sector or in the structure of the scalar potential. Most treatments in the literature focus on CP-violating Yukawa interactions of neutral scalars, which is an example of P-odd CP violation since it derives from the mixing of two C-even operators of opposite sign P. In contrast,...

We discuss signatures of CP-violating (CPV) two Higgs doublet models at LHC and future linear colliders, where CPV appears from Yukawa interactions and the Higgs potential. In particular, we consider the scenario with the Yukawa alignment to avoid tree level flavor changing neutral currents. In addition, we consider the Higgs alignment in which the couplings of the discovered Higgs boson are...

Vectorlike leptons are an intriguing possibility for physics beyond the Standard Model. This talk is concerned with the example of weak isosinglet vectorlike leptons that decay through a small mixing with the tau lepton, for which the discovery and exclusion reach of the Large Hadron Collider and future proposed hadron colliders is limited. For this minimal model, I will argue that an $e^+...

We study the search for Right Handed Neutrinos (RHN) at ILC. RHN are introduced by several extensions of the SM to explain the tiny neutrino mass. If RHN is a Majorana particle, RHN pair production is allowed in e−e+ collisions. We focus on RHN pair production based on a minimal U(1)B−L model. A distinctive signature is a pair of same sign leptons, a smoking-gun for Lepton Number Violation....

A light Higgs boson, with mass of the order of 100 GeV, is still not excluded by the existing experimental data, provided its coupling to gauge bosons is strongly suppressed compared to a SM-like Higgs boson at the same mass. Also other couplings of such a scalar could be very different from the SM predictions leading to non-standard decay paterns. Considered in the presented study is the...
