Very high energy(VHE)photons may have a higher survival rate than that expected in standard-model physics,as suggested by the recently reported gamma ray burst GRB221009A.While a photon-axion like particle(ALP)oscilla...

Pair production of the doubly charged leptons X±± via vector boson fusion (γγ, Zγ and WW) at the large hadron collider is studied. Our numerical results show that the cross section via Zγ fusion is very small....

A neutral Higgs boson is added into the traditional electroweak chiral Lagrangian by writing down all possible high dimension operators. The matter part of the Lagrangian is investigated in detail. We find that if Hig...

The pure annihilation type decays Dd^0→Фγand Bs→ργ receive only colour suppressed penguin contributions with a very small branching ratio in the standard model. When we include the previously neglected electroma...
