Self-Destructing Dark Matter

Yuval Grossman, Roni Harnik, Ofri Telem +1

We present Self-Destructing Dark Matter (SDDM), a new class of dark matter models which are detectable in large neutrino detectors. In this class of models, a component of dark mat…

Just a Taste: Lectures on Flavor Physics

Yuval Grossman, Philip Tanedo

We review the flavor structure of the Standard Model and the ways in which the flavor parameters are measured. This is an extended writeup of the TASI 2016 lectures on flavor physi…

Tree-level Quartic for a Holographic Composite Higgs

Csaba Csáki, Michael Geller, Ofri Telem

We present a new class of composite Higgs models where an adjustable tree-level Higgs quartic coupling allows for a significant reduction in the tuning of the Higgs potential. Our…

Baryon Number Violating Scatterings in Laboratories

S. -H. Henry Tye, Sam S. C. Wong

Earlier estimates have argued that the baryon number violating scattering cross-section in the laboratory is exponentially small so it will never be observed, even for incoming 2-p…

Trigonometric Parity for the Composite Higgs

Csaba Csáki, Teng Ma, Jing Shu

We identify trigonometric parity as the key ingredient behind models of neutral naturalness for the Higgs potential. We show that any symmetric coset space readily includes such a…

Detection of sub-MeV Dark Matter with Three-Dimensional Dirac Materials

Yonit Hochberg, Yonatan Kahn, Mariangela Lisanti +7

We propose the use of three-dimensional Dirac materials as targets for direct detection of sub-MeV dark matter. Dirac materials are characterized by a linear dispersion for low-ene…

Collider Probes of Axion-Like Particles

Martin Bauer, Matthias Neubert, Andrea Thamm

Axion-like particles (ALPs), which are gauge-singlets under the Standard Model (SM), appear in many well-motivated extensions of the SM. Describing the interactions of ALPs with SM…

Dark forces coupled to non-conserved currents

Jeff A. Dror, Robert Lasenby, Maxim Pospelov

New light vectors with dimension-4 couplings to Standard Model states have (energy / vector mass)^2 enhanced production rates unless the current they couple to is conserved. These…

Vector SIMP dark matter

Soo-Min Choi, Yonit Hochberg, Eric Kuflik +4

Strongly Interacting Massive Particles (SIMPs) have recently been proposed as light thermal dark matter relics. Here we consider an explicit realization of the SIMP mechanism in th…

Lepton-Jets and Low-Mass Sterile Neutrinos at Hadron Colliders

Sourabh Dube, Divya Gadkari, Arun M. Thalapillil

Sterile neutrinos, if they exist, are potential harbingers for physics beyond the Standard Model. They have the capacity to shed light on our flavor sector, grand unification frame…

Dark Spectroscopy

Yonit Hochberg, Eric Kuflik, Hitoshi Murayama

Rich and complex dark sectors are abundant in particle physics theories. Here we propose performing spectroscopy of the mass structure of dark sectors via mono-photon searches at l…

Phenomenology of ELDER Dark Matter

Eric Kuflik, Maxim Perelstein, Nicolas Rey-Le Lorier +1

We explore the phenomenology of Elastically Decoupling Relic (ELDER) dark matter. ELDER is a thermal relic whose present density is determined primarily by the cross-section of its…

Searching for Dark Matter with Neutron Star Mergers and Quiet Kilonovae

Joseph Bramante, Tim Linden, Yu-Dai Tsai

We identify new astrophysical signatures of dark matter that implodes neutron stars (NSs), which could decisively test whether NS-imploding dark matter is responsible for missing p…

Dynamics of Electroweak Phase Transition In Singlet-Scalar Extension of the Standard Model

Gowri Kurup, Maxim Perelstein

An addition to the Standard Model of a real, gauge-singlet scalar field, coupled via a Higgs portal interaction, can reopen the possibility of a strongly first-order electroweak ph…

New constraints on light vectors coupled to anomalous currents

Jeff A. Dror, Robert Lasenby, Maxim Pospelov

We derive new constraints on light vectors coupled to Standard Model (SM) fermions, when the corresponding SM current is broken by the chiral anomaly. Cancellation of the anomaly b…

LHC as an Axion Factory: Probing an Axion Explanation for with Exotic Higgs Decays

Martin Bauer, Matthias Neubert, Andrea Thamm

We argue that a large region of so far unconstrained parameter space for axion-like particles (ALPs), where their couplings to the Standard Model are of order $(0.01\!-\!1)\,\mbox{…

Viable Twin Cosmology from Neutrino Mixing

Csaba Csaki, Eric Kuflik, Salvator Lombardo

Twin Higgs models solve the little hierarchy problem without introducing new colored particles, however they are often in tension with measurements of the radiation density at late…

Daniel Aloni, Aielet Efrati, Yuval Grossman +1

Experimental measurements of the ratios () show a deviation from the Standard Model prediction. In…

The Maximally Symmetric Composite Higgs

Csaba Csaki, Teng Ma, Jing Shu

We present a novel class of calculable four dimensional composite pseudo-Goldstone boson Higgs models based on symmetric G/H coset spaces which contain a Higgs-parity operator V as…
