Dark Radiation from Neutrino Mixing after Big Bang Nucleosynthesis
Daniel Aloni, Melissa Joseph, Martin Schmaltz +1
A light ( MeV) dark fermion mixing with the Standard Model neutrinos can naturally equilibrate with the neutrinos via oscillations and scattering. In the presenc…
Measuring CP violation in using excited charm mesons
Daniel Aloni, Yuval Grossman, Abner Soffer
There is growing evidence for deviation from the standard model predictions in the ratios between semi-tauonic and semi-leptonic decays, known as the puzzle. If th…
Evaporating Axion Dark Matter and the Hubble Constant
Daniel Aloni, Hengameh Bagherian, Rashmish K. Mishra
Axion-like particles are a well-motivated dark matter candidate that can form a condensate with low momentum and high occupation number. In the presence of dark radiation, this con…
Revisiting leptonic nonunitarity
Daniel Aloni, Avital Dery
In the presence of extra neutrino states at high scales, the low-energy effective leptonic mixing matrix (LMM) is in general nonunitary. We revisit the question of what…
Testing Minimal Flavor Violation in Leptoquark Models of the Anomaly
Daniel Aloni, Avital Dery, Claudia Frugiuele +1
The anomaly can be explained by tree level exchange of leptoquarks. We study the consequences of subjecting these models to the principle of minimal flavor violation…
CMB constraints on primordial black hole dark matter
Daniel Aloni, Kfir Blum, Raphael Flauger
We revisit cosmic microwave background (CMB) constraints on primordial black hole dark matter. Spectral distortion limits from COBE/FIRAS do not impose a relevant constraint. Planc…
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 , resp…
Photoproduction of axion-like particles
Daniel Aloni, Cristiano Fanelli, Yotam Soreq +1
We explore the sensitivity of photon-beam experiments to axion-like particles (ALPs) with QCD-scale masses whose dominant coupling to the Standard Model is either to photons or glu…
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 predict…
Spontaneously Broken -Form U(1) Symmetries
Daniel Aloni, Eduardo GarcÃa-Valdecasas, Matthew Reece +1
Spontaneous breaking of symmetries leads to universal phenomena. We extend this notion to -form U(1) symmetries. The spontaneous breaking is diagnosed by a dependence of the…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
A Step in Understanding the Tension
Melissa Joseph, Daniel Aloni, Martin Schmaltz +2
Models of dark sectors with a mass threshold can have important cosmological signatures. If, in the era prior to recombination, a relativistic species becomes nonrelativistic and i…
Large BR(h->tau mu) in the MSSM?
Daniel Aloni, Yosef Nir, Emmanuel Stamou
We study how large the rate of the lepton-flavor violating Higgs decay h->tau mu can be in the (R-parity conserving) MSSM. We make no assumptions, such as universality or alignment…
A Step in Understanding the Hubble Tension
Daniel Aloni, Asher Berlin, Melissa Joseph +2
As cosmological data have improved, tensions have arisen. One such tension is the difference between the locally measured Hubble constant and the value inferred from the cosm…
Cosmological probes of Dark Radiation from Neutrino Mixing
Itamar J. Allali, Daniel Aloni, Nils Schöneberg
Models of stepped dark radiation have recently been found to have an important impact on the anisotropies of the cosmic microwave background, aiding in easing the Hubble tension. I…
Spontaneous CP Violation and Horizontal Symmetry in the MSSM: Toward Lepton Flavor Naturalness
Daniel Aloni, Pouya Asadi, Yuichiro Nakai +2
We study the contributions of supersymmetric models with a horizontal symmetry and only spontaneous CP breaking to various lepton flavor observables, such as and…
Coupling QCD-scale axion-like particles to gluons
Daniel Aloni, Yotam Soreq, Mike Williams
We present a novel data-driven method for determining the hadronic interaction strengths of axion-like particles (ALPs) with QCD-scale masses. Using our method, it is possible to c…
