B^\pm -> D K^\pm with direct CP violation in charm
Mario Martone, Jure Zupan
We investigate the implications of direct CP violation (CPV) on the determination of the unitarity triangle angle γ from B -> DK decays. We show that γ can still be extracted even…
Dark Matter Search at a Linear Collider: Effective Operator Approach
Yoonseok John Chae, Maxim Perelstein
Experiments at electron-positron colliders can search for dark matter particle pair-production in association with a photon. We estimate the sensitivity of this search at the propo…
SU(3) Sum Rules for Charm Decay
Yuval Grossman, Dean J Robinson
We present flavor SU(3) sum rules for and decay amplitudes, that are valid to second order in symmetry breaking by the strange quark mass spurion. Decay rate…
Neutralino Oscillations at the LHC
Yuval Grossman, Bibhushan Shakya, Yuhsin Tsai
We study a supersymmetric phenomenon that can give spectacular signals at the LHC: oscillations of neutralinos. Such oscillations can be naturally realised in R-symmetric models, w…
Lifting degeneracies in Higgs couplings using single top production in association with a Higgs boson
Marco Farina, Christophe Grojean, Fabio Maltoni +2
Current Higgs data show an ambiguity in the value of the Yukawa couplings to quarks and leptons. Not so much because of still large uncertainties in the measurements but as the res…
Mesino Oscillation in MFV SUSY
Joshua Berger, Csaba Csáki, Yuval Grossman +1
R-parity violating supersymmetry in a Minimal Flavor Violation paradigm can produce same-sign dilepton signals via direct sbottom-LSP pair production. Such signals arise when the s…
From Lagrangians to Events: Computer Tutorial at the MC4BSM-2012 Workshop
Stefan Ask, Neil D. Christensen, Claude Duhr +9
This is a written account of the computer tutorial offered at the Sixth MC4BSM workshop at Cornell University, March 22-24, 2012. The tools covered during the tutorial include: Fey…
A Higgslike Dilaton
Brando Bellazzini, Csaba Csáki, Jay Hubisz +2
We examine the possibility that the recently discovered 125 GeV higgs like resonance actually corresponds to a dilaton: the Goldstone boson of scale invariance spontaneously broken…
Testing BSM physics through correlations between flavor observables
Monika Blanke
I provide an overview of the connections between flavor violating observables in the K and B meson systems beyond the Standard Model (BSM). Model independent correlations, both in…
Electroweak Baryogenesis in R-symmetric Supersymmetry
R. Fok, Graham D. Kribs, Adam Martin +1
We demonstrate that electroweak baryogenesis can occur in a supersymmetric model with an exact R-symmetry. The minimal R-symmetric supersymmetric model contains chiral superfields…
XENON100 Implications for Naturalness in the MSSM, NMSSM and lambda-SUSY
Maxim Perelstein, Bibhushan Shakya
In a recent paper arXiv:1107.5048, we discussed the correlation between the elastic neutralino-nucleon scattering cross section, constrained by dark matter direct detection experim…
Momentum asymmetries as CP violating observables
Joshua Berger, Monika Blanke, Yuval Grossman +1
Three body decays can exhibit CP violation that arises from interfering diagrams with different orderings of the final state particles. We construct several momentum asymmetry obse…
Complete Tenth-Order QED Contribution to the Muon g-2
Tatsumi Aoyama, Masashi Hayakawa, Toichiro Kinoshita +1
We report the result of our calculation of the complete tenth-order QED terms of the muon g-2. Our result is a_μ^{(10)} = 753.29 (1.04) in units of (α/π)^5, which is about 4.5 s.d.…
Tenth-Order QED Contribution to the Electron g-2 and an Improved Value of the Fine Structure Constant
Tatsumi Aoyama, Masashi Hayakawa, Toichiro Kinoshita +1
This paper presents the complete QED contribution to the electron g-2 up to the tenth order. With the help of the automatic code generator, we have evaluated all 12672 diagrams of…
Composite Higgs Sketch
Brando Bellazzini, Csaba Csáki, Jay Hubisz +2
The coupling of a composite Higgs to the standard model fields can deviate substantially from the standard model values. In this case perturbative unitarity might break down before…
KeV Warm Dark Matter and Composite Neutrinos
Dean J Robinson, Yuhsin Tsai
Elementary keV sterile Dirac neutrinos can be a natural ingredient of the composite neutrino scenario. For a certain class of composite neutrino theories, these sterile neutrinos n…
A Fermionic Top Partner: Naturalness and the LHC
Joshua Berger, Jay Hubisz, Maxim Perelstein
Naturalness demands that the quadratic divergence of the one-loop top contribution to the Higgs mass be cancelled at a scale below 1 TeV. This can be achieved by introducing a ferm…
Testing for new physics in singly Cabibbo suppressed D decays
Yuval Grossman, Alexander L. Kagan, Jure Zupan
We devise tests for a new physics origin of the recently measured direct CP violation in singly Cabibbo suppressed D decays. The tests take the form of sum rules for the CP asymmet…
A consistent picture for large penguins in D -> pi+ pi-, K+ K-
Joachim Brod, Yuval Grossman, Alexander L. Kagan +1
A long-standing puzzle in charm physics is the large difference between the D0 -> K+ K- and D0 -> pi+ pi- decay rates. Recently, the LHCb and CDF collaborations reported a surprisi…
The birds and the Bs in RS: the b to s gamma penguin in a warped extra dimension
Monika Blanke, Bibhushan Shakya, Philip Tanedo +1
We calculate contributions to the photon and gluon magnetic dipole operators that mediate b -> s gamma and b -> d gamma transitions in the Randall-Sundrum model of a warped extra d…
SUSY_FLAVOR v2.5: a computational tool for FCNC and CP-violating processes in the MSSM
A. Crivellin, J. Rosiek, P. H. Chankowski +3
We present SUSY_FLAVOR version 2.5 - a Fortran 77 program that calculates low-energy flavor observables in the general -parity conserving MSSM. For a set of MSSM parameters as i…
Asymmetric Higgsino Dark Matter
Kfir Blum, Aielet Efrati, Yuval Grossman +2
In the supersymmetric framework, a higgsino asymmetry exists in the universe before the electroweak phase transition. We investigate whether the higgsino is a viable asymmetric dar…
Tenth-Order QED Contribution to the Lepton Anomalous Magnetic Moment -- Sixth-Order Vertices Containing an Internal Light-by-Light-Scattering Subdiagram
T. Aoyama, M. Hayakawa, T. Kinoshita +1
This paper reports the tenth-order QED contribution to the lepton g-2 from the gauge-invariant set, called Set III(c), which consists of 390 Feynman vertex diagrams containing an i…
Light Stops from Seiberg Duality
Csaba Csaki, Lisa Randall, John Terning
If low-energy supersymmetry is realized in nature, a seemingly contrived hierarchy in the squark mass spectrum appears to be required. We show that composite supersymmetric theorie…
