Finite-Temperature Instantons from First Principles
Thomas Steingasser, Morgane König, David I. Kaiser
We derive the finite-temperature quantum-tunneling rate from first principles. The rate depends on both real- and imaginary-time; we demonstrate that the relevant instantons should…

Higgs Criticality beyond the Standard Model
Thomas Steingasser, David I. Kaiser
Both parameters in the Higgs field's potential, its mass and quartic coupling, appear fine-tuned to near-critical values, which gives rise to the hierarchy problem and the metastab…

Gravity-improved metastability bounds for the Type-I Seesaw Mechanism
Garv Chauhan, Thomas Steingasser
Right-handed neutrinos (RHN) destabilize the electroweak vacuum by increasing its decay rate. In the SM, the latter is dominated by physics at the RG scale at which reaches its…
