Anomaly Detection In Action

A few weeks ago I posted here an idea of how one could design an algorithm that looks for new physics processes in Large Hadron Collider data, without giving the algorithm any knowledge whatsoever of how those new physics processes should behave. ...

Immortal: Quasiparticles Decay, But Identical Particle Entities Emerge From The Debris

The concept of quasiparticles was coined by Nobel laureate Lev Davidovich Landau, who used it to describe collective states of lots of particles or rather their interactions due to electrical or magnetic forces. Due to this interaction, several particles a ...

The Plot Of The Week- Detecting Dark Matter With Brownian Motion

I am reading a fun paper today, while traveling back home. I spent the past three days at CERN to follow a workshop on machine learning, where I also presented the Anomaly Detection algorithm I have been working on in the past few weeks (and about which I ...

The Plot Of The Week- Higgs Bosons Hiding Inside Jets

Particle physicists call "jet" the combined effect of many particles produced together when an energetic quark or gluon is kicked out of the hadron it called home, or when it is produced out of the blue by the decay of a massive particle.  The cl ...
