Could it be a particle that has negative mass ?
In this case it would not appear in the CERN.
I'm way out of my field so please anyone, correct me if I'm wrong.
The CERN is creating particles from pure energy, E=mc² means that if you focus a lot of energy in a single point some of the energy is turned into matter. From my understanding the generated matter is random particles.
Now if we want to create a particle with negative mass we need negative energy. What is negative energy? I have no idea but if we manage to focus a huge amount of negative energy we will get particles with negative mass.
Do we need negative energy?
Don't particles appear out of thin are and then collide again and disappear?
0 = E = -mc² + mc²
You can have negative mass without requiring negative energy.
If you created a negative mass particle at the same time as a positive mass particle, you'd essentially be able to do so with 0 or near 0 energy because they have opposite signs and would cancel out - negative energy plus positive energy. Free energy?
