I can provide you with some general information on the topic.
Supersymmetry (SUSY) is a theoretical framework in particle physics that proposes a symmetry between fermions and bosons, and it has been an active area of research for several decades. While SUSY has been an appealing idea due to its potential to solve certain problems in the Standard Model of particle physics, such as the hierarchy problem and the presence of dark matter, experimental evidence for supersymmetric particles has not yet been found.
The absence of direct experimental evidence for supersymmetry has led to some debate and speculation within the particle physics community. While there are researchers who remain hopeful and continue to explore the possibilities of supersymmetry, there are also those who have become more skeptical or have shifted their focus to alternative theories.
It's important to note that the scientific process involves ongoing investigation and refinement of theories based on new experimental data and theoretical developments. The difficulty in making progress in any particular area of research can depend on various factors, such as the energy scales at which supersymmetric particles are expected to be discovered, the sensitivity of current experimental detectors, and the availability of new experimental data.
In summary, while some particle physicists may have adjusted their expectations or shifted their focus due to the absence of direct experimental evidence for supersymmetry, it does not necessarily mean that everyone has given up on the idea. The field of particle physics is dynamic and continues to evolve as new data and theoretical advancements emerge.
