We propose to search for wrong displaced vertices, where decay products of the secondary vertex move towards the primary vertex instead of away from it, as a signature for microscopic violation of causality. We analyze in detail the leptonic sector of the recently proposed Lee-Wick Standard Model, which provides a well motivated framework to study acausal effects. We find that, assuming Minimal Flavor Violation, the Lee-Wick partners of the electron, e and , can produce measurable wrong…

Feasibility study for the measurement of acausal particles with wrong displaced vertices at the LHC particle physics

In Particle Physics, many extensions to the Minimal Standard Model have been proposed trying to solve the hierarchy problem. Most of those theories imply the existence of new particles that could be

Causality-violating Higgs singlets at the LHC

We construct a simple class of compactified five-dimensional metrics which admits closed timelike curves (CTCs), and derive the resulting CTCs as analytic solutions to the geodesic equations of

Radiation bounce from the Lee-Wick construction?

It was recently realized that matter modeled by the scalar field sector of the Lee-Wick standard model yields, in the context of a homogeneous and isotropic cosmological background, a bouncing

The Lee-Wick standard model

We construct a modification of the standard model which stabilizes the Higgs mass against quadratically divergent radiative corrections, using ideas originally discussed by Lee and Wick in the

Extensions of the Standard Model Higgs Sector

The Standard Model is regarded as one of the most successful scientific theories, but there is compelling evidence that it is an incomplete theory of particle physics. There is currently no

Causality, unitarity and stability in quantum gravity: a non-perturbative perspective

Resumming quantum fluctuations at the level of the gravitational path integral is expected to result in non-local effective actions and thus in a non-trivial momentum dependence of the propagator.

The other Higgses, at resonance, in the Lee-Wick extension of the Standard Model

Within the framework of the Lee-Wick Standard Model (LWSM) we investigate Higgs pair production gg → h0h0, $ gg \to {h_0}{\tilde{p}_0} $ and top pair production $ gg \to \bar{t}t $ at the Large

Custodial isospin violation in the Lee-Wick standard model

We analyze the tension between naturalness and isospin violation in the Lee-Wick standard model (LW SM) by computing tree-level and fermionic one-loop contributions to the post-LEP electroweak



Searching for Lee-Wick Gauge Bosons at the LHC

In an extension of the Standard Model(SM) based on the ideas of Lee and Wick, Grinstein, O'Connell and Wise have found an interesting way to remove the usual quadratically divergent contributions to

Unique Identification of Lee-Wick Gauge Bosons at Linear Colliders ∗†

Grinstein, O'Connell and Wise have recently presented an extension of the Standard Model (SM), based on the ideas of Lee and Wick (LW), which demonstrates an interesting way to remove the

Electroweak precision constraints on the Lee-Wick standard model

We perform an analysis of the electroweak precision observables in the Lee-Wick Standard Model. The most stringent restrictions come from the S and T parameters that receive important tree level and

Neutrino masses in the Lee-Wick standard model

Recently, an extension of the standard model based on ideas of Lee and Wick has been discussed. This theory is free of quadratic divergences and hence has a Higgs mass that is stable against

Lee–Wick theories at high temperature

Massive vector scattering in Lee-Wick gauge theory

We demonstrate that amplitudes describing scattering of longitudinally polarized massive vector bosons present in non-Abelian Lee-Wick gauge theory do not grow with energy and, hence, satisfy the

New Higgs physics from the lattice

We report the first results from our comprehensive lattice to ol set to explore non-perturbative aspects of Higgs physics in the Standard Model. We demonstrate in Higgs-Yukawa models that Higgs mass
