What happens to Q-balls if is so large?
Nobuyuki Sakai, Takashi Tamaki
In the system of a gravitating Q-ball, there is a maximum charge inevitably, while in flat spacetime there is no upper bound on in typical models such as the Affl…
What are universal features of gravitating Q-balls?
Takashi Tamaki, Nobuyuki Sakai
We investigate how gravity affects Q-balls by exemplifying the case of the Affleck-Dine potential . Surprisingly, stable Q-balls with arbitrarily…
Gravitating Q-balls in the Affleck-Dine mechanism
Takashi Tamaki, Nobuyuki Sakai
We investigate how gravity affects "Q-balls" with the Affleck-Dine potential . Contrary to the flat case, in which equilibrium s…
How does gravity save or kill Q-balls?
Takashi Tamaki, Nobuyuki Sakai
We explore stability of gravitating Q-balls with potential via catastrophe theory, as an extension of our previous work on Q-balls with…
Unified picture of Q-balls and boson stars via catastrophe theory
Takashi Tamaki, Nobuyuki Sakai
We make an analysis of Q-balls and boson stars using catastrophe theory, as an extension of the previous work on Q-balls in flat spacetime. We adopt the potential $V_3(ϕ)={m^2\over…
