SuperSymetry, the theory that poses all known basic particles have a heavier particle “Superparter”, has been the Superstar of theoretical physics for the last century. His advocates have been the best hope for particle physics, for example, to solve mysteries such as dark matter. Skeptics protested privileged treatment at the absence of experimental validity. CERN Hadron colllid (LHC), the largest and strongest accelerator of the world, found to find evidence of SuperSymmetry after finding his atlas and CMS experiments Higgs Boson. Although more than a decade of βut search, two experiments are still empty.
Cultural grips in supersymetry has been so powerful to discover the end of theory, it should never come. For now this moment could be here: Atlas and CMS teams no longer have a working group dedicated to SuperSymetry.
Such a work team are the axes of Atlas and CMS research, organize hundreds of analyzes according to thematic umbrellas. In the early 2010 decade, when the Proton Proton collision began, the supermetria team of each experiment had a way for the search for “new physics”. One day dedicated teams would not be surprised.

“Supersymety was a tremendous industry since the 90s.
Belief “almost biblical”
To understand the appeal of Supersymmetry, it must be returned to the beginning of the 1970s. Beyond the standard model, basic known particles and their relationships, according to the theory that describes the theories of the Soviet Union, has been a pioneering U.S. supermetry as a possible solution.
Theorists soon realized that the mathematical tools involved in “susty” (theories used theoretically) can solve many problems in physics. The supermarkets were considered candidates prepared for dark matter particles, and Syri offered possible paths for quantum gravity. In addition, the scaffold was a key argument for building chain theory and LHC. As the number of publications published in Susy changed, the theory became a cultural phenomenon, which performs books, articles and interviews that carry out books and interviews that almost cancellations are being removed.
“When I was a student,” Susy’s existence was a part of the researchers who were working on the issue. This is certainly reflected in the procurement of practices and was linked to the superposimetry that many higher research teams had.
All the time, there was no experimental discovery, and the super-super-super-patterns have been significant, especially for arbitrary features. Models came with many variables that came with unknown and tuning values required to explain the lack of the natural world of the natural world. Were calculations to predict the masses of superparters tendency to rise revision After each null, in many generations that collide.
“Physicists are usually Faddish, following trends,” says Nobel Laureate Sheldon Glashow, a professor at Boston University and the standard model of the standard model. “Sometimes believing in SuperSymmetry seemed almost as Bible.”
Desperately looking suspicious
However, the lightest superparents in the simple sons should be At the disposal of the LHC’s collision, otherwise they could not resolve the problems they asked for.
In 2015, the innovative version of LHC almost doubled its collision energy from electrons 13, but the analyzes remained empty handed, maintaining the palpable consignment of defenders and opponents. Ambroad enthusiasm For Susy When online to wede.

A quick decade. Last year Atlas restructured research work, dividing Susy studies among the three groups. As a result, the Higgs, Bosa Multi-Bosos and Susy searches (HMBS) was created, is an open call to name this group.
Two years ago, Sussy team started taking Syri’s analyzes (even if they are usually associated with the measurements associated with the equal “signature” combinations. To reflect this change, the group was newer in January (NPS) physics.
“The group restructuring had two main reasons: Make the search groups of the same size and signature to go to studies with similar methods of ideas,” says Cécile Cailllek, CMS ‘NPS team’s researcher. It added approximately one third of the new group analysis. A researcher at the University of Edinburgh, a researcher at the University of Edinburgh, offers the motivations behind Anlas’s reorganization and HMBS provides a constant job of Susy: “It still includes a very dedicated Susy Focus,” he explained.
Falkowski not involved with both teams offers its translation: “They are not enough motivational people to get out of business,” he said. “Moreover, it also has little sense from a practical point of view to maintain supersimetric searches separate from other searches.
Big bets
The same atlas and CMS have studied the signatures of the correct models and have seen nothing new, but there are always other options. Howard Baer, a teacher at the University of Oklahoma, explains that there are higher models and very sophisticated models that are very plausal, with subtle signatures that can be perceived in the upcoming LHC data in the coming years. “The rise of the simplified model of LHC analysis has led to a decrease in communication between theoretical and experimentalists,” he noted. Problems, as he sees, “are a very explainting theory, with the same weight next to theories that solve basic problems in physics (Susy).”
Although many models are well motivated in theoretical terms, almost unlimited varieties have long been for Sustry Skeptics. This gypsy is occasionally avoided through betting: some significantly Physicists possess bet Very specific supersymmetric knowledge in LHC. Most have been accepted, but some bets are officially unresolved due to the disagreements between the aspects of the actual situation on Supersymetry’s true situation.
However, it is a bigger bet that represents individual squabbles to internalize the integrity of the particles: Supersymetry’s commitment to succeeded the path to a new generation of stronger experiments. Instead, Susy’s discovery has not been paired with the discovery of standard standard models planned, it is more difficult to justify the main international investment required for larger and best accelerators. Glamashow notes, “The earth is well, and nothing has shown. Things will change and spread the next great collision when we will not see, but for our children.”
If a project materializes, it is another hard option: Collider should collision with higher energy to be higher new particles or more specific measurements of popular particles (such as Higgs) to reveal new effects? Only machine Cannot do both correctly.
These thoughts are echoed in Stoical predictions of Falkowski: “Beyond the standard physics, it will gradually be less interest, less of the paper, less experimental, search for new particles,” he noted. “The turn will be toward the” accuracy “of physics, or” Collider “from physics.”
And in the present, unlike in recent decades, the researcher who works Syrus will no longer be known in the labor market. Baer warns that few young physicists make funding proposals for Susy search.
The extensive length of a fruitless collective search can throw the shade at this point. But it can also prove that it is Susy’s greatest heritage, reporting the way you change things. Borrow from another area, “When you find something to be discarded, you need to consider what you need, in mind in the store.
About LHC’s constant searches, one thing is sure, as a physicist atlas comment Online in September, “Susy is still a nice theory, (but) doesn’t make sense that a privileged theory is compared to others.”
