Exact All-Level Positivity of the Bosonic Veneziano Amplitude
Qi Chen, Yuan Yin
Tree-level partial-wave unitarity of the open bosonic Veneziano amplitude follows indirectly from the no-ghost theorem, but a direct proof from the beta function has been missing a…
Heavy-particle production during inflation and its gravitational-wave signal
Qi Chen, Yuan Yin
We study a mechanism for producing heavy particles during inflation through a transient quadratic -breaking interaction of a complex scalar coupled derivatively to the inflat…
Large non-Gaussianities corresponding to first-order phase transitions during inflation
Haipeng An, Qi Chen, Yuhang Li +1
In this study, we explore the back reaction of phase transitions in the spectator sector on the inflaton field during slow-roll inflation. Due to the significant excursion of the i…
A model for inflaton induced baryogenesis and its phenomenological consequences
Haipeng An, Qi Chen, Yuan Yin
In this study, we introduce a novel approach aimed at addressing the longstanding baryon-anti-baryon asymmetry conundrum. Our proposed mechanism suggests that baryon numbers were g…
