Can Higgs experiment give other new particles

In summary: It's a common misconception that the LHC is supposed to "find new particles", but it's more accurate to say that we are trying to "map out the energy range of the Standard Model". In summary, The Large Hadron Collider (LHC) experiment was designed to discover the Higgs boson, but it also has the potential to detect other new elementary particles. The LHC detectors have published technical reports of their searches for new particles, such as the SupersymmetryPublicResults and ExoticsPublicResults. The LHC experiments use triggers to filter out irrelevant data and focus on interesting events, including those with Higgs particles and other potential new particles. It is possible that there are no other particles in the LHC's energy

The Higgs experiment was intended to discover Higgs boson. But, can measurement data give any other new elementary particles? Or, are the measurements so specific, that other particles cannot be seen?

The LHC detector groups are certainly looking for signs of new particles. For example, the published technical reports of the Atlas group regarding these searches are at

https://twiki.cern.ch/twiki/bin/view/AtlasPublic/ExoticsPublicResults

To a certain extent, they need to know what to look for. There are far too many collisions occurring within the detectors to store all of the data, let alone analyze. Some information on the trigger system at Atlas can probably be found from the references here.

There is no "Higgs experiment". The LHC collides protons with protons, and those collisions produce all sorts of particles as long as they are not too heavy. The production of a Higgs boson is just one of many processes which can happen in an interaction. If there are other new particles, they could be produced as well, and the LHC detectors look for those particles, too.

At electron-positron-colliders (like LEP, or the planned ILC), this is different - usually you have to choose which process you want to study, and adjust the energy accordingly.

At least, Higgs experiment has very large fitered base of data, thus, all data are not collected for further analysis. Data are filtered for properties of Higgs, isn't it?

It is strange to me that no other particles were discovered, so this filtering is the only explanation for me, am I right?

The LHC experiments use sophisticated triggers to keep only interesting events, right. There are many different triggers - some of them are designed for events with Higgs particles, some of them are designed for supersymmetric particles, some of them are designed for "everything decaying to high-energetic muons" and so on. A lot of time was spent to make sure that basically everything detectable has some trigger line in order to find it.

"There are no other particles in this energy range" is a perfectly valid option.
 

Related to Can Higgs experiment give other new particles

1. How can the Higgs experiment give rise to new particles?

The Higgs experiment at the Large Hadron Collider (LHC) collides particles at incredibly high energies, recreating conditions similar to the early universe. In this intense environment, the Higgs field is believed to give mass to particles, and any new particles that interact with the Higgs field could be produced.

2. What kinds of new particles can the Higgs experiment potentially discover?

The Higgs experiment is primarily searching for new particles that are predicted by the Standard Model of particle physics, such as supersymmetric particles or extra dimensions. However, it could also potentially discover completely new, unexpected particles that could revolutionize our understanding of the universe.

3. Is it possible for the Higgs experiment to confirm the existence of dark matter?

Although the Higgs experiment is not specifically designed to detect dark matter, it could indirectly confirm its existence if it produces new particles that could be candidates for dark matter. These particles would interact very weakly with regular matter, making them difficult to detect, but their presence could be inferred from their effects on other particles in the experiment.

4. How would the discovery of new particles from the Higgs experiment impact our current understanding of the universe?

If the Higgs experiment does discover new particles, it could provide valuable insights into the fundamental laws of nature and potentially fill in gaps in our current understanding of the universe. It could also help explain phenomena such as dark matter and dark energy, which are currently not well understood.

5. What are the potential applications of the Higgs experiment's discovery of new particles?

The discovery of new particles from the Higgs experiment could have a wide range of applications, from advancing technologies in fields such as medicine and energy production to helping us better understand the origins of the universe. It could also lead to new theories and models that could guide future scientific research and advancements.
