Despite its remarkable success, the Standard Model (SM) of particle physics does not address key facts revealed by cosmological and astrophysical observations. Until now, no signs of new physics have been discovered in laboratory experiments, leaving unclear what is the path chosen by Nature for the physics beyond the SM (BSM). I will discuss in this talk how indirect signals from Dark Matter (DM) might help us in this challenging "theoretical selection problem", with implications on foundational aspects of BSM physics. I will illustrate this point with possible DM interpretations of recent anomalies in multimessenger observations of energetic radiation of Galactic and extragalactic origin.

Jens Dyvik will present us the "Fellesverkstedet".

https://www.fablabs.io/fellesverkstedet

Jens Dyvik is a designer specialized in global collaboration and local manufacturing. He works with emotional connections between people and products, and aims to create services and products that help make those connections meaningful.

In 2013 he concluded a two year research world tour, where he worked at open collaborative workspaces on all corners of the world. He is currently applying this research into open design and personal manufacturing in Oslo, enabling him to make a living from an open and sharing design approach. He is also a co-founder of Fellesverkstedet, a super-FabLab in the making in Oslo.

Jens Dyvik er en designer spesialisert i globalt samarbeide og lokal produksjon. I april 2013 avsluttet han en toårig FabLab forskningreise hvor han jobbet på åpne digitale produksjonsverksteder jorden rundt. Han bruker denne kunnskapen om kortreist design, personlig produksjon og globalt samarbeide på sitt design studio i Oslo. Dette gjør han i stand til å leve av en åpen og delende tilnærming til design. Han er også co-founder av Fellesverkstedet, et åpent verksted for produksjon i Oslo.

Although there is substantial gravitational evidence for the existence of dark matter, its nature as a new particle beyond the Standard Model remains one of the biggest mysteries in modern astrophysics. The favourite theoretical model, Cold Dark Matter (CDM), assumes that non-gravitational dark matter interactions are irrelevant for galaxy formation and evolution.

Surprisingly, there is no strong evidence for the CDM hypothesis. Current astronomical observations allow significant departures that have a relevant impact on our understanding of how galaxies form and evolve. Moreover, the observed properties of the smallest galaxies have been consistently in conflict with the predictions of the CDM model.

In this talk, I will argue that to explain galaxy formation and evolution in the broadest sense, an effective dark matter theory must contain a wider range of dark matter particle physics without spoiling the success of CDM in reproducing the large-scale structure of the Universe, while addressing its outstanding challenges at the scales of individual galaxies.

Ivica Picek, Univ. of Zagreb

After the discovery of the Higgs boson, searching for the dark matter (DM) is one of the main targets for the LHC. In light of evidence for neutrino mass it would be appealing that DM particles account for a solution to the small neutrino mass. A radiative neutrino mass realization dubbed  "scotogenic" (with DM particles in a loop) imposes an exactly conserved Z_2 symmetry to eliminate tree-level neutrino masses and to simultaneously stabilize a DM candidate.

In this talk I will discuss the possibility to avoid such ad hoc Z_2 symmetry: either by promoting it to a local gauge U(1)_D symmetry or by requiring that it arises "accidentally" (on account of the SM symmetry and a choice of the field content). In this context, I will discuss the testability of Majorana singlet, triplet  and quintet DM candidates at the LHC.

The search for the gamma-rays which are presumably produced in dark matter annihilations is hindered by the existence of large, and still poorly understood, astrophysical backgrounds. In this talk we will emphasize the importance of sharp spectral features for the identification of a dark matter signal. We will review the status of the search of the various spectral features that arise in Particle Physics scenarios and we will discuss the interplay with other search strategies.

Searches for particle physics beyond the Standard Model come in many forms, from searches for new particles at accelerators to gamma-ray and neutrino telescopes, cosmic ray detectors and ultra-clean experiments deep underground.  Efforts to combine multiple search channels in 'global fits' to new physics scenarios typically consider only a subset of the available channels, and apply them to a very small range of possible theories. Astroparticle searches in particular are usually only included in a very approximate way, if at all.  In this talk I will review recent progress in improving this situation, and preview some of the future developments and challenges in this field.
