CGG POP-UP SHOW | May 13th 2015 | art space tetra | Fukuoka Japan

The Contemporary Guerilla Gallery Berlin is a project by a group of Berlin-based artists. The experimental project explores new ways of dealing with the contemporary art market. Part of the concept of CGG Berlin is independent art selling on eBay, another part is making pop-up exhibitions without external curatorial influence.

At art space tetra we show video works of five of the CGG artists. The video works have a documentary character and thematize the process of art production.

At the opening Hannah Reber and Gert-Jan Akerboom will be present and give a brief introduction of the project and answer questions after the screening.

The CGG Berlin pop-up at art space tetra shows works by:

Where Does The Mass Of A Proton Come From?

“It is very accurately known how large the average gluon density is inside a proton. What is not known is exactly where the gluons are located inside the proton. We model the gluons as located around the three valance quarks. Then we control the amount of fluctuations represented in the model by setting how large the gluon clouds are, and how far apart they are from each other.”

If you divide the matter we know into progressively smaller and smaller components, you’d find that atomic nuclei, made of protons and neutrons, compose the overwhelming majority of the mass we understand. But if you look inside each nucleon, you find that its constituents – quarks and gluons – account for less than 0.2% of their total mass. The remaining 99.8% must come from the unique binding energy due to the strong force. To understand how that mass comes about, we need to better understand not only the average distribution of sea quarks and gluons within the proton and heavy ions, but to reveal the fluctuations in the fields and particle locations within. The key to that is deep inelastic scattering, and we’re well on our way to uncovering the cosmic truths behind the origin of matter’s mass.

the most hypnotic thing you´ll see today.
