Neutrino Mass, Vacuum Stability and Higgs Inflation with Vector-Like Quarks and a Single Right-Handed Neutrino
Canan Karahan
We investigate a Standard Model extension containing degenerate down-type isosinglet vector-like quarks (VLQs) with masses and Yukawa couplings $y_{\mathcal D}…
Large Field Polynomial Inflation in Palatini Gravity
Nilay Bostan, Canan Karahan, Ozan Sargın
In this paper, we employ the Palatini formalism to investigate the dynamics of large-field inflation using a renormalizable polynomial inflaton potential in the context of …
Inflation in Symmergent Metric-Palatini Gravity
Nilay Bostan, Canan Karahan, Ozan Sargın
In this paper, we study the cosmological inflation phenomenon in symmergent gravity theory. Symmergent gravity is a novel framework which merges gravity and the standard model (SM)…
Dimensional Regularization in Quantum Field Theory with Ultraviolet Cutoff
Durmus Demir, Canan Karahan, Ozan Sargın
In view of various field-theoretic reasons, in the present work, we study the question of if the usual dimensional regularization can be extended to quantum field theories with an…
Ricci-Determinant Gravity: Dynamical Aspects and Astrophysical Implications
Hemza Azri, K. Yavuz Ekşi, Canan Karahan +1
The Palatini gravitational action is enlarged by an arbitrary function of the determinants of the Ricci tensor and the metric, . The res…
Type-3/2 Seesaw Mechanism
Durmus Demir, Canan Karahan, Ozan Sargın
Type-I seesaw provides a natural explanation for the tiny neutrino masses. The right-handed neutrino masses it requires are, however, too large to keep the Higgs boson mass at its…
