Particle FeverDavid KAPLAN

I describe the analysis of the Standard Model of particle physics that has led a generation to believe that there is (accessible) physics beyond it. I also introduce the idea ...

Effective Lagrangian for the HiggsAdam FALKOWSKI

I will summarize the status of the Higgs boson after the first run of the LHC. The emphasis will be on interpreting the Higgs results as constraints on physics beyond ...

Soft matter in motionEric LAUGA

The cellular world is inhabited by a myriad of microorganisms able to self- propel, including many bacteria, spermatozoa, ciliates, and plankton. Here, we focus on the biophysics of ciliary locomotion ...

Complex extension of quantum mechanicsCarl BENDER

The average quantum physicist on the street would say that a quantum- mechanical Hamiltonian must be Dirac Hermitian (invariant under combined matrix transposition and complex conjugation) in order to guarantee ...

The structure of amplitudes in gauge theoryRuth BRITTO

Observing new physics at hadron colliders requires a detailed description of multi-particle scattering events. It is not practical to evaluate Feynman diagrams directly for all significant processes. Moreover, adding all ...

Motile MatterSriram RAMASWAMY

Active Matter is composed of particles each supplied with energy which it dissipates, often resulting in systematic movement. Examples include living organisms, their motile constituents and some surprising mechanical and ...
