彩色玻璃凝聚体中质子-质子碰撞中张量介子的产生

Tensor Meson Production in Proton-Proton Collisions from the Color Glass Condensate

Francois Fillion-Gourdeau, Sangyong Jeon

摘要:

计算了高能质子-质子碰撞中$f_{2}$张量介子产生的包含截面。我们使用一个有效的理论,从张量介子的优势假设,耦合胶子$f_{2}$介子的启发。我们计算微分截面的$k_{\perp}$ -因式分解和彩色玻璃冷凝形式主义在低密度制度。我们表明,这两个形式主义是等价的,这个具体的观察。最后,我们通过比较未积分胶子分布函数的不同参数化的理论预言,研究了$f_{2}$介子的唯象。我们发现,$f_{2}$介子生产是另一个可观察到的,可以用来把这些分布的约束。

英文摘要:

We compute the inclusive cross-section of $f_{2}$ tensor mesons production in proton-proton collisions at high-energy. We use an effective theory inspired from the tensor meson dominance hypothesis that couples gluons to $f_{2}$ mesons. We compute the differential cross-section in the $k_{\perp}$-factorization and in the Color Glass Condensate formalism in the low density regime. We show that the two formalisms are equivalent for this specific observable. Finally, we study the phenomenology of $f_{2}$ mesons by comparing theoretical predictions of different parameterizations of the unintegrated gluon distribution function. We find that $f_{2}$-meson production is another observable that can be used to put constraints on these distributions.
