Color Breaking Baryogenesis
Michael J. Ramsey-Musolf, Peter Winslow, Graham White
We propose a scenario that generates the observed baryon asymmetry of the Universe through a multi--step phase transition in which SU(3) color symmetry is first broken and then res…
Singlet-Catalyzed Electroweak Phase Transitions in the 100 TeV Frontier
Ashutosh V. Kotwal, Michael J. Ramsey-Musolf, Jose Miguel No +1
We study the prospects for probing a gauge singlet scalar-driven strong first order electroweak phase transition with a future proton-proton collider in the 100 TeV range. Singlet-…
The Higgs Portal and Cosmology
Ketevi Assamagan, Chien-Yi Chen, John Paul Chou +19
Higgs portal interactions provide a simple mechanism for addressing two open problems in cosmology: dark matter and the baryon asymmetry. In the latter instance, Higgs portal inter…
Stop-Catalyzed Baryogenesis Beyond the MSSM
Andrey Katz, Maxim Perelstein, Michael J. Ramsey-Musolf +1
Non-minimal supersymmetric models that predict a tree-level Higgs mass above the Minimal Supersymmetric Standard Model (MSSM) bound are well motivated by naturalness considerations…
TeV Lepton Number Violation: From Neutrinoless Double Beta Decay to the LHC
Tao Peng, Michael J. Ramsey-Musolf, Peter Winslow
We analyze the sensitivity of next-generation tonne-scale neutrinoless double -decay () experiments and searches for same-sign di-electrons plus jets at the Large Hadron C…
Singlet-Catalyzed Electroweak Phase Transitions and Precision Higgs Studies
Stefano Profumo, Michael J. Ramsey-Musolf, Carroll L. Wainwright +1
We update the phenomenology of gauge singlet extensions of the Standard Model scalar sector and their implications for the electroweak phase transition. Considering the introductio…
Tracking Down the Top Quark Forward-Backward Asymmetry with Monotops
Abhishek Kumar, John N. Ng, Andrew Spray +1
We revisit the possibility that the top quark forward-backward asymmetry arises from the on-shell production and decay of scalar top partners to top-antitop pairs with missing tran…
Top Quark Forward-Backward Asymmetry and Anomalous Right-Handed Charge Currents
John N. Ng, Peter T. Winslow
Recent measurements of the top quark forward-backward asymmetry at the Tevatron could hint at new physics with an unexpected flavor structure. The significance of such an abnormal…
Anomalous B meson mixing and baryogenesis in a two Higgs doublet model with top-charm flavor violation
Sean Tulin, Peter Winslow
There exist experimental hints from the B sector for CP violation beyond the Standard Model (SM) CKM paradigm. An anomalous dimuon asymmetry was reported by the D0 collaboration, w…
Multi-State Dark Matter from Spherical Extra Dimensions
Peter T. Winslow, Kris Sigurdson, John N. Ng
We demonstrate a new model which uses an ADD type braneworld scenario to produce a multi-state theory of dark matter. Compactification of the extra dimensions onto a sphere leads t…
Neutron-Antineutron Oscillations in a Warped Extra Dimension
Peter T. Winslow, John N. Ng
We investigate neutron-antineutron oscillations in the Randall-Sundrum warped extra dimensional scenario. The four dimensional effective strengths of the relevant operators that in…
