Barr-Zee diagrams at a high-energy muon collider
Journal of High Energy PhysicsThe sensitivity of electron EDM experiments has been increasing at a rapid pace, and could yield indications of new physics in the coming decade. An intriguing possibility is that an EDM signal could be generated by new, electroweak-charged particles at ...

The BSM Physics Case of the ILC
, 2016 In this talk I summarize the physics case of the International Linear Collider (ILC) focusing on its potential towards discovery, discrimation or disentanglement of new physics beyond the Standard Model (BSM).Comment: 8 pages, 2 figures, Talk presented ...

Journal of High Energy PhysicsWe consider extending the Standard Model by an anomaly-free and possibly flavour non-universal U(1) X gauge symmetry, whose breaking gives a Z′ boson that does not affect electroweak precision observables at tree-level or via 1-loop renormalisation group

Positivity from J-Basis operators in the standard model effective Field Theory
Journal of High Energy PhysicsIn the effective field theory (EFT), the positivity bound on dim-8 effective operators tells us that the s 2 contribution in the scattering amplitude of 2-to-2 process geometrically corresponds to the convex cone composed of the ultraviolet (UV) states ...

The bearing capacity of footings on sand with a weak layer
, 2017 Minor details of the ground, such as thin weak layers, shear bands and slickensided surfaces, can substantially affect the behaviour of soil–footing and other geotechnical systems, despite their seeming insignificance. In this paper, the influence of the

Quantum detection of new physics in top-quark pair production at the LHC
Journal of High Energy PhysicsThe recent observation of entanglement between top and anti-top quarks at the LHC opens the way to interpreting collider data with quantum information tools. In this work we investigate the relevance of quantum observables in searches of new physics.

Complete UV resonances of the dimension-8 SMEFT operators
Journal of High Energy PhysicsThe effective field theory approach parameterizes the low energy behaviors of all possible ultraviolet (UV) theories in a systematic way. One of the most important tasks is thus to find the connection between the effective operators and their UV origins.

Measuring the polarization of boosted, hadronic W bosons with jet substructure observables
Journal of High Energy PhysicsIn this work, we present a new technique to measure the longitudinal and transverse polarization fractions of hadronic decays of boosted W bosons. We introduce a new jet substructure observable denoted as p θ , which is a proxy constructed purely out of ...

General form of effective operators from hidden sectors
Journal of High Energy PhysicsWe perform a model-independent analysis of the dimension-six terms that are generated in the low energy effective theory when a hidden sector that communicates with the Standard Model (SM) through a specific portal operator is integrated out.

Physics Case for the ILC Project: Perspective from Beyond the Standard Model
, 2013 The International Linear Collider (ILC) has recently proven its technical maturity with the publication of a Technical Design Report, and there is a strong interest in Japan to host such a machine.
