and leptonic decays as probes of solutions to the puzzle
Daniel Aloni, Aielet Efrati, Yuval Grossman +1
Experimental measurements of the ratios () show a deviation from the Standard Model prediction. In…
Exotic colored scalars at the LHC
Kfir Blum, Aielet Efrati, Claudia Frugiuele +1
We study the phenomenology of exotic color-triplet scalar particles with charge and . If is a non-singlet of representation, mass…
The phenomenology of the di-photon excess and within 2HDM
Aielet Efrati, Jernej F. Kamenik, Yosef Nir
The diphoton excess around GeV observed at ATLAS and CMS can be interpreted as coming from and , the neutral components of a second Higgs doublet. If so, then th…
On a possible large width 750 GeV diphoton resonance at ATLAS and CMS
Daniel Aloni, Kfir Blum, Avital Dery +2
The ATLAS and CMS experiments at the LHC have reported an excess of diphoton events with invariant mass around 750 GeV, with local significance of about and , respec…
Electroweak constraints on flavorful effective theories
Aielet Efrati, Adam Falkowski, Yotam Soreq
We derive model-independent constraints arising from the Z and W boson observables on dimension six operators in the effective theory beyond the Standard Model. In particular, we d…
Constraining the Higgs-Dilaton with LHC and Dark Matter Searches
Aielet Efrati, Eric Kuflik, Shmuel Nussinov +2
We study a scenario in which the dilaton, a pseudo-Goldstone boson of the spontaneous breaking of conformal symmetry, provides a portal between dark matter and the visible sector.…
Simplified Models for Dark Matter and Missing Energy Searches at the LHC
Jalal Abdallah, Adi Ashkenazi, Antonio Boveia +22
The study of collision events with missing energy as searches for the dark matter (DM) component of the Universe are an essential part of the extensive program looking for new phys…
Model building for flavor changing Higgs couplings
Avital Dery, Aielet Efrati, Yosef Nir +2
If () or () decays are observed, it will be a clear signal of new physics. We investigate whether natural and viable flavor m…
Asymmetric lepton-flavor violating Higgs decays
Shikma Bressler, Avital Dery, Aielet Efrati
We introduce a new method to search for the lepton-flavor violating Higgs decays and in the leptonic decay channel. In particular, the Standar…
What if
Aielet Efrati, Yosef Nir
A measurement of the Higgs trilinear self coupling will test the Standard Model Higgs potential. But can it reveal information that cannot be learned otherwise? By analyz…
Subtleties in the BaBar measurement of time-reversal violation
Elaad Applebaum, Aielet Efrati, Yuval Grossman +2
A first measurement of time-reversal (T) asymmetries that are not also CP asymmetries has been recently achieved by the BaBar collaboration. We analyze the measured asymmetries in…
Higgs couplings to fermions: 2HDM with MFV
Avital Dery, Aielet Efrati, Gudrun Hiller +2
We clarify several subtleties concerning the implementation of minimal flavor violation (MFV) in two Higgs doublet models. We derive all the exact and approximate predictions of MF…
A tale of two Higgs
Aielet Efrati, Daniel Grossman, Yonit Hochberg
A new boson with mass ~125 GeV and properties similar to the Standard Model Higgs has been discovered by both the ATLAS and CMS collaborations, with significant observation in the…
What if BR(h-->μμ)/BR(h-->ττ) does not equal m_μ^2/m_τ^2?
Avital Dery, Aielet Efrati, Yonit Hochberg +1
Measurements of the Yukawa couplings of the recently discovered boson h to fermion pairs will provide a new arena for studying flavor physics. We analyze the lessons that can be le…
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…
