Накратко на български

Търсенето на тъмната материя се фокусира върху частици от типа WIMP, които взаимодействат много слабо с останалата материя. По-добрите софтуерни инструменти за анализ ще помогнат за разбирането на природата на тези частици и създаването на по-ефективни уреди за тяхното откриване.

Global searches for dark matter and new physics with GAMBIT using effective field theory

"The search for astrophysical Dark Matter is one of longest and most dramatic ongoing quests in all of science. There is abundant circumstantial evidence that Dark Matter exists, however it has so far eluded all attempts to discover its nature. There are many ideas for what this nature may be, but a frontrunner for many years has been the WIMP, or ""weakly interacting massive particle"". The WIMP would be a new fundamental particle, like electrons, photons, or quarks, but one which interacts very weakly with all the others, such that only its gravitational influence can be easily observed. Understanding the nature of Dark Matter, while not a pressing social issue, is one of the most profound questions open to the human race. Like the discovery of electrons, x-rays, quarks, or gravitational waves, the impact upon human society, technology, and knowledge will likely be revolutionary. This project pushes forward the search for WIMPS (and particle dark matter in general) by improving the computational and statistical tools available to physicists to analyse the results of experimental searches for Dark Matter. Namely it extends an open-source statistical package known as GAMBIT to allow sophisticated analysis of a wide range of WIMP-like dark matter models that can be analysed in the framework of ""effective field theory"", a sub-class of quantum field theories in which particle interactions are modelled in terms of their effective low-energy properties rather than hypothetical new high-energy physics. With these improved tools, theoretical physicists will be better equipped to guide their experimental colleagues in constructing new apparatuses to search for the most promosing Dark Matter candidates. On top of this, they may be able to find hints of Dark Matter by combining the results of many experiments together, something generally outside the scope of each individual experiment's goals and capabilities."

Цел на проекта

The nature of dark matter (DM) is arguably the biggest mystery in fundamental physics. Many experimental efforts are underway which aim to detect this elusive matter and measure its properties, using a wide variety of techniques, however to make full use of this data a combined statistical analysis must be performed which makes use of the data from all these experiments simultaneously, and compares this data to the predictions of many different theories while including all uncertainties, correlations and theoretical nuances self-consistently. Analyses of this kind are known as ""global fits"". I propose to use a newly developed, open-source global-fitting tool called GAMBIT to perform the largest and most robust combined statistical analysis of DM data to date. To do this I will extend the capabilities of GAMBIT to allow it to work with a class of models known as ""effective theories"" which efficiently parameterise the degrees of freedom relevant to experiments at a particular energy scale, so that a global fit can be performed in a fully model-independent way. This will require several connected layers of effective theory to be utilised, to account for the different energy scales involved in the diverse set of DM experiments currently underway. The project is highly interdisciplinary and makes use of recent theoretical developments and experimental results in high energy physics, particle astrophysics, astronomy, nuclear physics, and computational statistics. The proposal will generate a transfer of knowledge to the host institution while developing the candidate's theoretical expertise in new directions, particularly particle astrophysics. The results of the project will be of wide use to the dark matter community, both in terms of direct analysis results and via the development of open-source computational tools for use in future analyses, and will provide robust guidance to experimentalists as to which dark matter candidates are the most promising.""
