Particle Desert and New Physics

In summary, the conversation discusses the possibility of a "particle desert" where new particles do not exist between the weak and Planck scale but new physics may still be present. Examples are given, such as distinguishing quantum interpretations and the existence of a scalar field with light bosons. The conversation then moves on to the objects that can exist in the quantum vacuum, including fermions, gauge bosons, gravitons, spacetime manifolds, branes, superstrings, and various quantum interpretations. The laws of physics and the possibility of an unpaid theoretical debt from the past are also brought up. The conversation ends with a reminder to adhere to site rules and focus on mainstream science rather than personal theories.

Is it possible there is a particle desert where there are no new particles between the weak and Planck scale yet there is new physics before the Planck scale.. can you give examples how this can occur?

An example. If we can distinguish quantum interpretations.. won't this be new physics that won't affect the scale between the weak and Planck scale.. please give other examples... also I'm thinking of scalar field which has bosons so light it escaped detection.. what other possibilities?

Quantum vacuum is home to quantum fields of all kinds.. and they have quanta..

So maybe particle desert with new physics means something else besides quantum field?

What else is there in the quantum vacuum? How about dark energy... which is related to general relativity. Can general relativity be said to be inside the quantum vacuum? or separate?

If you have special configuration of manifolds like branes folded into specific shapes that doesn't have particle contribution.. then perhaps this is stuff of new physics after the Particle Desert?

The Quantum vacuum is said to be Lorentz invariant.. and even though we have unlimited energy supply in the quantum vacuum.. we can't tap it because the energy is the same and you need energy differential to extract energy. So perhaps study of special configurations of manifolds can maybe affect the quantum vacuum and make some kind of "lift" effect that can make you navigate the quantum vacuum by influencing the zero point energy? Any reference about this?

Or just general...

What are (please enumerate all) the objects that can possibly exist in the quantum vacuum...

1. Spin 1/2 Fermion, Spin 1 Gauge Bosons
2. Spin 0 Scalar Higgs Field with non zero vev
3. Spin 2 gravitons
4. Spacetime manifolds
5. Branes or Calabi-Yau manifolds (doesn't this produce the vacuum itself?)
6. Superstrings
7. Pilot Wave, Quantum Potential and other quantum interpretation things.
8. Dirac Sea particles
9. What else? (Beyond the Standard Model)?

What else can exist in the quantum vacuum that won't violate the laws of physics of the vacuum or physics in general? Can you enumerate all of them? I'd like to see a thorough list.​

This is good to reflect or ponder what is life/physics after a possible Particle Desert.

We are waiting for the future to bring the answer. Our mind does not admit another expectation. We prepare ourselves to accept what the future may bring, from a sane and simple retouch to a maddening and complicated spasm. But the future must bring it, because we are sure that no debt of the past has remained unpaid.

Are we sure ? Very safe? Has nothing remained unpaid and we bet life that this is the case? Or betting on life would be too much risk? Could the difficulties be related to an unpaid theoretical debt of the past? Would it be a waste of time to thoroughly review the full implications of the unification that laid the foundations of modern physics, that is, the Maxwell electrodynamics?

This thread very speculative in nature. We need to see peer reviewed articles to continue the discussion otherwise we will have to close and warn.

Please take some to read our site rules. We try to help students learn mainstream science not discuss personal theories or speculative science.
 

1. What is the Particle Desert and why is it important in physics?

The Particle Desert refers to a gap in the energy spectrum of particles, specifically between the energy scales of 1 GeV and 1 TeV. This gap is significant because it represents a lack of evidence for new particles or interactions at these energy scales, which has led to the search for new physics beyond the Standard Model.

2. What is the Standard Model and how does it relate to the Particle Desert?

The Standard Model is the current theory that describes the fundamental particles and their interactions in the universe. It has been successful in explaining and predicting many phenomena, but it also has limitations, such as not being able to explain gravity or dark matter. The Particle Desert is a region where the Standard Model alone cannot fully explain the observed behavior of particles, leading to the search for new physics theories.

3. What are some proposed explanations for the Particle Desert?

There are several theories that attempt to explain the Particle Desert, such as Supersymmetry, Extra Dimensions, and Technicolor. These theories propose the existence of new particles or interactions that could fill the gap in the energy spectrum and provide a more complete understanding of the universe.

4. How are scientists studying the Particle Desert and searching for new physics?

Scientists are using various methods to study the Particle Desert and search for new physics, such as colliding particles at high energies in particle accelerators like the Large Hadron Collider, analyzing data from cosmic rays, and conducting experiments to detect rare processes or particles. These efforts require collaboration and advanced technology to collect and analyze vast amounts of data.

5. What impact could new physics discoveries have on our understanding of the universe?

The discovery of new physics beyond the Standard Model could revolutionize our understanding of the universe. It could help explain unanswered questions such as the origin of dark matter and the imbalance between matter and antimatter. It could also lead to new technologies and advancements in fields such as energy and medicine.
