The Minimal Model of a Diphoton Resonance: Production without Gluon Couplings

Csaba Csaki, Jay Hubisz, John Terning

We consider the phenomenology of a resonance that couples to photons but not gluons, and estimate its production rate at the LHC from photon-photon fusion in elastic pp scattering…

Flavour Fields in Steady State: Stress Tensor and Free Energy

Avik Banerjee, Arnab Kundu, Sandipan Kundu

The dynamics of a probe brane in a given gravitational background is governed by the Dirac-Born-Infeld action. The corresponding open string metric arises naturally in studying the…

Elastically Decoupling Dark Matter

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

We present a novel dark matter candidate, an Elastically Decoupling Relic (ELDER), which is a cold thermal relic whose present abundance is determined by the cross-section of its e…

Rossby Wave Instability and Long-Term Evolution of Dead Zones in Protoplanetary Discs

Ryan Miranda, Dong Lai, Heloise Meheut

The physical mechanism of angular momentum transport in poorly ionized regions of protoplanetary discs, the dead zones (DZs), is not understood. The presence of a DZ naturally lead…

Watch-Bot: Unsupervised Learning for Reminding Humans of Forgotten Actions

Chenxia Wu, Jiemi Zhang, Bart Selman +2

We present a robotic system that watches a human using a Kinect v2 RGB-D sensor, detects what he forgot to do while performing an activity, and if necessary reminds the person usin…

Decision making by Berry's flux

Benjamin O. Sung, Michael J. Lawler

Order by disorder is a decision making process for frustrated systems but often leads to simple answers. We study order by disorder in the kagome Kondo model known for its complexi…

Efficient heat-bath sampling in Fock space

Adam Holmes, Hitesh J. Changlani, C. J. Umrigar

We introduce an algorithm for sampling many-body quantum states in Fock space. The algorithm efficiently samples states with probability approximately proportional to an arbitrary…

The Flavor of the Composite Twin Higgs

Csaba Csaki, Michael Geller, Ofri Telem +1

The assumption of anarchic quark flavor puts serious stress on composite Higgs models: flavor bounds imply a tuning of a few per-mille (at best) in the Higgs potential. Composite t…
