天体非粒子物理学

Astro Unparticle Physics

A. Freitas, D. Wyler

摘要:

我们调查的所有味盲CP守恒非粒子运营商的第五力实验,恒星冷却,超新星爆炸的影响,并比较彼此之间的限制,并与那些可从对撞机实验。一般来说,天体物理界是相当强的,但它们强烈依赖于非粒子算子的维数d_U。当d_U=1时,第五种力的实验给出了非常强的边界,而当d_U=2时,恒星冷却和超新星冷却的边界更接近,其中恒星冷却是最严格的。矢量非粒子耦合的边界一般比标量耦合的边界强。

英文摘要:

We investigate the effects of all flavor blind CP-conserving unparticle operators on 5th force experiments, stellar cooling, supernova explosions and compare the limits with each other and with those obtainable from collider experiments. In general, astrophysical bounds are considerably stronger, however they depend strongly on the dimension d_U of the unparticle operator. While for d_U=1, 5th force experiments yield exceedingly strong bounds, the bounds from stellar and supernova cooling are more comparable for d_U=2, with stellar cooling being most restrictive. Bounds on vectorial unparticle couplings are generally stronger than those on scalar ones.
