Is this predicted by Standard Model or not ? --- And, if it is a "new physics" what exactly type of "new physics" is it

...says physicist and BaBar team leader Hassan Jawahery of the University of Maryland, College Park. The D-meson's jump to antimatter could be due to the particle's interactions with forces that are currently unknown, he says: "[it] could be the result of the Standard Model, or it could be new physics."

Physicist Jon Rosner of the University of Chicago agrees that it's too soon to know the significance of the find. Although the detection of D-meson mixing is "a long-sought goal of particle physics," he says, "the theoretical predictions for this effect--even those based on the Standard Model--have been all over the map," so it's "good to see the mixing actually observed."

If it isn`t, I think we should forget about D-mesons and move immediately to E-mesons. However, I must remind everyone of the well-known dangers of going to F-mesons or beyond.

I would say that this new evidence of D-meson mixing is very exciting and has the potential to reveal new insights into the fundamental forces of nature. The Standard Model, which is the current theory that describes the behavior of particles and their interactions, does not fully explain this phenomenon. This could mean that there is a new type of physics at play, which would be a groundbreaking discovery.

There are several theories that propose new physics beyond the Standard Model, such as supersymmetry or extra dimensions. It is too early to determine which one, if any, could explain this D-meson mixing. Further research and experiments are needed to fully understand this phenomenon and its implications for our understanding of the universe.

Regardless of whether it is predicted by the Standard Model or not, this discovery highlights the importance of continued exploration and discovery in the field of particle physics. It is through these experiments and observations that we can push the boundaries of our knowledge and potentially uncover new laws of nature.
