Color Octet Leptogenesis
Marta Losada, Sean Tulin
We study the implications for generating the cosmological baryon asymmetry through leptogenesis in the recent model of Fileviez Perez and Wise, which provides a new mechanism for g…
Yukawa Interactions and Supersymmetric Electroweak Baryogenesis
Daniel J. H. Chung, Bjorn Garbrecht, Michael J. Ramsey-Musolf +1
We analyze the quantum transport equations for supersymmetric electroweak baryogenesis including previously neglected bottom and tau Yukawa interactions and show that they imply th…
The Effect of the Sparticle Mass Spectrum on the Conversion of B-L to B
Daniel J H Chung, Bjorn Garbrecht, Sean Tulin
In the context of many leptogenesis and baryogenesis scenarios, B-L (baryon minus the lepton number) is converted into B (baryon number) by non-perturbative B+L violating operators…
Pion Leptonic Decays and Supersymmetry
Michael Ramsey-Musolf, Shufang Su, Sean Tulin
We compute supersymmetric contributions to pion leptonic (π_{l2}) decays in the Minimal Supersymmetric Standard Model (MSSM). When R-parity is conserved, the largest contributions…
Supersymmetric Contributions to Weak Decay Correlation Coefficients
Stefano Profumo, Michael J. Ramsey-Musolf, Sean Tulin
We study supersymmetric contributions to correlation coefficients that characterize the spectral shape and angular distribution for polarized muon- and beta-decays. In the minimal…
Yukawa and Tri-scalar Processes in Electroweak Baryogenesis
Vincenzo Cirigliano, Christopher Lee, Michael J. Ramsey-Musolf +1
We derive the contributions to the quantum transport equations for electroweak baryogenesis due to decays and inverse decays induced by tri-scalar and Yukawa interactions. In the M…
