An O(750) GeV Resonance and Inflation
Yuta Hamada, Toshifumi Noumi, Gary Shiu +1
We study the possibility of a heavy scalar or pseudoscalar in TeV-scale beyond the Standard Model scenarios being the inflaton of the early universe in light of the recent O(750) G…
Echoes of Inflationary First-Order Phase Transitions in the CMB
Hongliang Jiang, Tao Liu, Sichun Sun +1
Cosmological phase transitions (CPTs), such as the Grand Unified Theory (GUT) and the electroweak (EW) ones, play a significant role in both particle physics and cosmology. In this…
Z' models for the LHCb and g-2 muon anomalies
Ben Allanach, Farinaldo S. Queiroz, Alessandro Strumia +1
We revisit a class of Z' explanations of the anomalies found by the LHCb collaboration in decays, and show that the scenario is tightly constrained by a combination of constrai…
Large Two-loop Effects in the Higgs Sector as New Physics Probes
Sichun Sun
We consider a simple Higgs portal model in beyond the standard model scenario: an extra real gauge singlet scalar that couples to the Higgs. We calculate the higher-loop correction…
