TASI Lectures on Non-Supersymmetric BSM Models
Csaba Csáki, Salvator Lombardo, Ofri Telem
These lectures provide a self-contained introduction to the essential aspects of non-supersymmetric beyond the Standard Model (BSM) physics for beginning graduate students who are…
Continuum Naturalness
Csaba Csáki, Gabriel Lee, Seung J. Lee +2
We present a novel class of composite Higgs models in which the top and gauge partners responsible for cutting off the Higgs quadratic divergences form a continuum. The continuum s…
Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
David Curtin, Marco Drewes, Matthew McCullough +85
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of…
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…
Traces of a triboson resonance
J. A. Aguilar-Saavedra, J. H. Collins, S. Lombardo
We show that the relatively small but coincident excesses observed around 2 TeV in the ATLAS Run 1 and Run 2 hadronic diboson searches --- when a cut on the number of tracks in the…
Novel kinematics from a custodially protected diphoton resonance
Jack H. Collins, Csaba Csaki, Jeff Asaf Dror +1
We study a simple, well-motivated model based on a custodial symmetry which describes the tree-level production of a 750 GeV diphoton resonance from a decay of a singly produced ve…
Gluon vs. Photon Production of a 750 GeV Diphoton Resonance
Csaba Csaki, Jay Hubisz, Salvator Lombardo +1
The production mechanism of a 750 GeV diphoton resonance, either via gluon or photon fusion, can be probed by studying kinematic observables in the diphoton events. We perform a de…
Searching for Displaced Higgs Decays
Csaba Csaki, Eric Kuflik, Salvator Lombardo +1
We study a simplified model of the SM Higgs boson decaying to a degenerate pair of scalars which travel a macroscopic distance before decaying to SM particles. This is the leading…
Phenomenology of a Long-Lived LSP with R-Parity Violation
Csaba Csaki, Eric Kuflik, Salvator Lombardo +2
We present the leading experimental constraints on supersymmetric models with R-parity violation (RPV) and a long-lived lightest superpartner (LSP). We consider both the well-motiv…
