Revisiting Uraltsev's BPS limit for Heavy Quarks
Johannes Heinonen, Thomas Mannel
Motivated by the recent experimental data of the values of the Heavy Quark Expansion parameters, in particular the spin-orbit and Darwin terms, we argue that nature actually may be…
Improved Estimates for the Parameters of the Heavy Quark Expansion
Johannes Heinonen, Thomas Mannel
We give improved estimates for the non-perturbative parameters appearing in the heavy quark expansion for inclusive decays. While the parameters appearing in low orders of this exp…
Lorentz invariance in heavy particle effective theories
Johannes Heinonen, Richard J. Hill, Mikhail P. Solon
Employing induced representations of the Lorentz group (Wigner's little group construction), formalism for constructing heavy particle effective Lagrangians is developed, and Lagra…
5D UED: Flat and Flavorless
Csaba Csáki, Johannes Heinonen, Jay Hubisz +2
5D UED is not automatically minimally flavor violating. This is due to flavor asymmetric counter-terms required on the branes. Additionally, there are likely to be higher dimension…
Odd Decays from Even Anomalies: Gauge Mediation Signatures Without SUSY
Csaba Csaki, Johannes Heinonen, Jay Hubisz +1
We analyze the theory and phenomenology of anomalous global chiral symmetries in the presence of an extra dimension. We propose a simple extension of the Standard Model in 5D whose…
A Weakly Coupled Ultraviolet Completion of the Littlest Higgs with T-parity
Csaba Csaki, Johannes Heinonen, Maxim Perelstein +1
We construct a weakly coupled, renormalizable ultraviolet completion of the Littlest Higgs model with T-parity (LHT), based on an SU(5)xSU(2)xU(1) gauge theory with a discrete Z_2…
