Global fits of scalar singlet dark matter with GAMBIT

Jonathan M. Cornell

The wide range of probes of physics beyond the standard model leads to the need for tools that combine experimental results to make the most robust possible statements about the va…

Analyzing the CP Nature of a New Scalar Particle via S->Zh Decay

Martin Bauer, Matthias Neubert, Andrea Thamm

Scalar particles which are singlets under the Standard Model gauge group are generic features of many models of fundamental physics, in particular as possible mediators to a hi…

Exclusive Weak Radiative Higgs Decays in the Standard Model and Beyond

Stefan Alte, Matthias König, Matthias Neubert

We perform a detailed study of the exclusive Higgs decays and , where is a pseudoscalar or vector meson, using the QCD factorization approach. We allow for t…

Current status of MSSM Higgs sector with LHC 13 TeV data

Rahool Kumar Barman, Biplob Bhattacherjee, Arghya Choudhury +3

ATLAS and CMS collaborations have reported the results on the Higgs search analyzing fb data from Run-II of LHC at 13 TeV. In this work, we study the Higgs sector…

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…

Co-Decaying Dark Matter

Jeff Asaf Dror, Eric Kuflik, Wee Hao Ng

We propose a new mechanism for thermal dark matter freezeout, termed Co-Decaying Dark Matter. Multi-component dark sectors with degenerate particles and out-of-equilibrium decays c…

Directional Detection of Dark Matter with Two-Dimensional Targets

Yonit Hochberg, Yonatan Kahn, Mariangela Lisanti +2

We propose two-dimensional materials as targets for direct detection of dark matter. Using graphene as an example, we focus on the case where dark matter scattering deposits suffic…

Factorization and Resummation for Jet Processes

Thomas Becher, Matthias Neubert, Lorena Rothen +1

From a detailed analysis of cone-jet cross sections in effective field theory, we obtain novel factorization theorems which separate the physics associated with different energy sc…

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…

A Diphoton Resonance from Bulk RS

Csaba Csaki, Lisa Randall

Recent LHC data hinted at a 750 GeV mass resonance that decays into two photons. A significant feature of this resonance is that its decays to any other Standard Model particles wo…

Diphoton Resonance from a Warped Extra Dimension

Martin Bauer, Clara Hoerner, Matthias Neubert

We argue that extensions of the Standard Model (SM) with a warped extra dimension, which successfully address the hierarchy and flavor problems of elementary particle physics, can…

750 GeV Di-photon Excess and Strongly First-Order Electroweak Phase Transition

Maxim Perelstein, Yu-Dai Tsai

A new scalar particle, coupled to photons and gluons via loops of vector-like quarks, provides a simple theoretical interpretation of the 750 GeV diphoton excess reported by the ex…

Probing a slepton Higgs on all frontiers

Carla Biggio, Jeff Asaf Dror, Yuval Grossman +1

We study several aspects of supersymmetric models with a symmetry where the Higgs doublet is identified with the superpartner of a lepton. We derive new, stronger bounds o…

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…
