60. Study of non-linear evolution of the hadron structure within QCD

Štěpán Mayer

9/19/24, 9:30 AM

While quantum chromodynamics (QCD) allows the calculation of processes governed by the strong interraction, trying to describe more complex objects like nucleons requires us to simplify the theory with a model. One such simplification is the dipole model accompanied by the Balitsky-Kovchegov (BK) equation. By numerically solving the BK equation, we can calculate the scattering amplitude and...

61. Incoherent J/𝝍 production at large |𝒕| identifies the onset of saturation at the LHC

Alexandra Ridziková

9/19/24, 9:50 AM

The study of incoherent production of a vector meson in diffractive processes provides information about the inner composition of the target hadron at the partonic level. The incoherent cross section is sensitivite to fluctuations in the configuration of the color field of the target. The energy-dependent hotspot model, based on the color dipole approach, incorporates subnucleon degrees of...

62. The Balitsky-Kovchegov equation and dipole orientation

Matěj Vaculčiak

9/19/24, 10:10 AM

A solution of the target-rapidity Balitsky-Kovchegov (BK) equation is presented considering, for the first time, the complete impact-parameter dependence, i.e. including the orientation of the dipole with respect to the impact-parameter vector. To address the non-local behaviour introduced in the target-rapidity formulation of the BK equation, three different prescriptions are considered to...

64. NLO BK

Marek Matas (České vysoké učení technické v Praze)

9/19/24, 10:30 AM

The Balitsky-Kovchegov evolution equation tells us much about the gluonic structure of hadronic targets in accelerator experiments. As its leading order form has been around for decades with great successes in high-energy phenomenology, the next-to-leading order version (yielding a more accurate description of the scattering process) proves to be a tough nut to crack. In this talk, we will crack it.

67. Dark matter

Adam Červenka

9/19/24, 11:10 AM

Dark matter is an astrophysical phenomenon of our time. Apart from observations of its effects on objects in the Universe, it has still not been detected directly on Earth. Its detection is a matter of current research, with limits to the possibility of simultaneous detection assumed based on its velocity distribution. This thesis discusses methods for accelerating dark matter. In particular,...

65. Dark photons from light and white colour

Jesus Guillermo Contreras

9/19/24, 11:30 AM

The concept of dark matter is introduced along with the idea of portals that allow the interaction of the Standard Model and the Dark sectors.
The photon portal is discussed, in particular in the context of diffractive photoproduction of dark photons. Predictions for this process are presented and the amount of expected events in future facilities is discussed for different parameters of the...

66. Numerical integration

Marek Matas (České vysoké učení technické v Praze)

9/19/24, 11:50 AM

Solving problems in contemporary physics often comes hand in hand with the need for accurate numerical integration. With every additional dimension that needs to be integrated over, this problem becomes increasingly more difficult and at some point unsolvable. One possible way to tackle this issue comes with Monte Carlo Importance Sampling integration. I will introduce this method along with...
