The Silence of the Dipoles: Accidental Symmetries in Lepton Flavor
Andrea Di Lecce, Majid Ekhterachian, Marko Pesut +1
Upcoming experiments are set to dramatically improve the search for charged lepton flavor violation, with the sensitivity to the rates of decay and conversion…
The Bearable Inhomogeneity of the Baryon Asymmetry
Hengameh Bagherian, Majid Ekhterachian, Stefan Stelzl
We study the implications of precision measurements of light-element abundances, in combination with the Cosmic Microwave Background, for scenarios of physics beyond the Standard M…
Conformal Leptogenesis in Composite Higgs Models
Kaustubh Agashe, Peizhi Du, Majid Ekhterachian +3
We study the generation of the baryon asymmetry in Composite Higgs models with partial compositeness of the Standard Model (SM) fermions and heavy right-handed neutrinos, developin…
Tetraquarks at large and large
Héloïse Allaman, Majid Ekhterachian, Filippo Nardi +2
We study tetraquarks in large QCD with heavy quarks, in the domain where non-relativistic quantum mechanics offers an adequate approximation. Within the regime of validity of t…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
Snowmass2021 White Paper: Collider Physics Opportunities of Extended Warped Extra-Dimensional Models
Kaustubh Agashe, Jack H. Collins, Peizhi Du +5
While the warped extra-dimensional models provide an attractive solution to both the gauge and the flavor hierarchy problems, the mass scale of new particles predicted by the minim…
Sleptonic SUSY: From UV Framework to IR Phenomenology
Kaustubh Agashe, Majid Ekhterachian, Zhen Liu +1
We study an attractive scenario, "Sleptonic SUSY", which reconciles the GeV Higgs scalar and the non-observation of superpartners thus far with potentially pivotal roles for…
The Muon Smasher's Guide
Hind Al Ali, Nima Arkani-Hamed, Ian Banta +31
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advan…
Bounds on Gauge Bosons Coupled to Non-conserved Currents
Majid Ekhterachian, Anson Hook, Soubhik Kumar +1
We discuss new bounds on vectors coupled to currents whose non-conservation is due to mass terms, such as . Due to the emission of many final state longitudinally…
Phase Transitions from the Fifth Dimension
Kaustubh Agashe, Peizhi Du, Majid Ekhterachian +2
We study the cosmological transition of 5D warped compactifications, from the high-temperature black-brane phase to the low-temperature Randall-Sundrum I phase. The transition proc…
LHC Signals for KK Graviton from an Extended Warped Extra Dimension
Kaustubh Agashe, Majid Ekhterachian, Doojin Kim +1
We analyze signals at the Large Hadron Collider (LHC) from production and decay of Kaluza-Klein (KK) gravitons in the context of "extended" warped extra-dimensional models, where t…
Cosmological Phase Transition of Spontaneous Confinement
Kaustubh Agashe, Peizhi Du, Majid Ekhterachian +2
The dynamics of a cosmological (de)confinement phase transition is studied in nearly conformally invariant field theories, where confinement is predominantly spontaneously generate…
Natural Seesaw and Leptogenesis from Hybrid of High-Scale Type I and TeV-Scale Inverse
Kaustubh Agashe, Peizhi Du, Majid Ekhterachian +3
We develop an extension of the basic inverse seesaw model which addresses simultaneously two of its drawbacks, namely, the lack of explanation of the tiny Majorana mass term fo…
Hybrid seesaw leptogenesis and TeV singlets
Kaustubh Agashe, Peizhi Du, Majid Ekhterachian +3
The appealing feature of inverse seesaw models is that the Standard Model (SM) neutrino mass emerges from the exchange of TeV scale singlets with sizable Yukawa couplings, which ca…
