Relevant Operators of Particle Physics and Cosmology

Cem Eroncel
Abstract: Although the Standard Model of Particle Physics can reproduce the results of all the experiments performed to this date, it can only be an effective theory of fundamental physics. However, treating the Standard Model this way brings its own set of challenges; namely, the coefficients of relevant operators become extremely sensitive to UV physics. The relevant operator of the Standard Model is the Higgs mass which causes the ”hierarchy problem”, while the cosmological constant term of cosmology results in the ”cosmological constant problem”. In this thesis defense, I will discuss about how these issues can guide us in the pursuit of searching for new physics, both from a model building perspective and from a phenomenological perspective.

Mirror neutron stars

TL;DR: The fundamental nature of dark matter is entirely unknown as discussed by the authors , and a compelling candidate is twin Higgs mirror matter, invisible hidden-sector cousins of the Standard Model particles and forces.

Gravitational waves

TL;DR: In this article, the authors analyzed the gravitational waves within the spinor theory of gravity and compared it with the General Relativity proposal, and showed that a gravitational wave may occur if the effective gravitational metric induced by the spinorial field is Ricci flat.

Self-similar pressure oscillations in neutron star envelopes as probes of neutron star structure

TL;DR: In this article, the eigenmodes of acoustic oscillations of high multipolarity l ∼ 100-1000 and high frequency (∼100 kHz) localized in neutron star envelopes are studied.

Moments of inertia of neutron stars in relativistic mean field theory: the role of the isovector scalar channel

TL;DR: In this article, the moments of inertia of neutron stars possessing various stellar masses are studied within the density dependent relativistic mean field (RMF) theory, and the results indicate that the crustal moment of inertia as a more sensitive probe of the neutron-star matter EOS than the total one, and demonstrate that the isovector scalar meson-nucleon couplings could exert influence over the physics of pulsar glitches.
