Hidden Spin-3/2 Field in the Standard Model
Durmuş Demir, Canan Karahan, Beste Korutlu +1
Here we show that a massive spin-3/2 field can hide in the SM spectrum in a way revealing itself only virtually. We study collider signatures and loop effects of this field, and de…
Softly Fine-Tuned Standard Model and the Scale of Inflation
Beste Korutlu
The direct coupling between the Higgs field and the spacetime curvature, if finely tuned, is known to stabilize the Higgs boson mass. The fine-tuning is soft because the Standard M…
Higgsed Stueckelberg Vector and Higgs Quadratic Divergence
Durmus Ali Demir, Canan Nurhan Karahan, Beste Korutlu
Here we show that, a hidden vector field whose gauge invariance is ensured by a Stueckelberg scalar and whose mass is spontaneously generated by the Standard Model Higgs field cont…
Effects of a Real Singlet Scalar on Veltman Condition
Canan Nurhan Karahan, Beste Korutlu
We revisit the fine-tuning problem in the Standard Model (SM) and show the modification in Veltman condition by virtue of a minimally-extended particle spectrum with one real SM ga…
Dark Matter from Conformal Sectors
Durmus A. Demir, Mariana Frank, Beste Korutlu
We show that a conformal-invariant dark sector, interacting conformally with the Standard Model (SM) fields through the Higgs portal, provides a viable framework where cold dark ma…
Saving the fourth generation Higgs with radion mixing
Mariana Frank, Beste Korutlu, Manuel Toharia
We study Higgs-radion mixing in a warped extra dimensional model with Standard Model fields in the bulk, and we include a fourth generation of chiral fermions. The main problem wit…
