Probing the Exotic Particle Content Beyond the Standard Model

We explore the possible exotic particle content beyond the standard model by examining all its scalar bilinear combinations. We categorize these exotic scalar fields and show that without the suppression of (A) their Yukawa couplings with the known quarks and leptons, and (B) the trilinear couplings among themselves, most are already constrained to be very heavy from the nonobservation of proto...

Probing physics beyond the standard model from lepton sector

The Standard Model (SM) is the most successful model to explain physics below the weak scale. The recent results for sin 2β or sin 2φ1 by Belle [1] and Babar [2] are converging, and they are consistent with the Kobayashi-Maskawa mechanism [3]. Also, the precision measurements of the electroweak parameters suggest the light SM Higgs boson such as mh ∼ 196GeV (95%CL) [4]. Now we are waiting for s...

Decays Probing Physics Beyond the Standard Theory

In the last 50 years we have seen how an initially ad-hoc and not widely accepted theory of the strong and electroweak interactions (Standard Theory: ST) has correctly predicted the entire accelerator based experimental observations with incredible accuracy (with the important exception of neutrino oscillation experiments). Decays of the ST particles (quarks and leptons), which are rare due to ...

Particle Dark Matter from Physics Beyond the Standard Model

So far the existence of the dark matter (DM) is our best experimental evidence for new physics beyond the Standard Model. The most recent WMAP data [1] confirm the standard cosmological model and precisely pin down the amount of cold dark matter as 0.094 < ΩCDMh 2 < 0.129, in accord with earlier indications. Nevertheless, the exact nature of the dark matter still remains a mystery, as all known...

Neutrino masses and particle physics beyond the standard model

The evidence for non-vanishing neutrino masses from solar and atmospheric neutrinos provides the first solid hint towards physics beyond the standard model. A full reconstruction of the neutrino spectrum may well provide a key to the theoretical structures underlying the standard model such as supersymmetry, grand unification or extra space dimensions. In this article we discuss the impact of a...
