Prompt neutrinos and intrinsic charm at SHiP

Journal of High Energy Physics, 2019
We present a new evaluation of the far-forward neutrino plus antineutrino flux and number of events from charm hadron decays in a 400 GeV proton beam dump experiment like the Search for Hidden Particles (SHiP).

On the short distance nonperturbative corrections in heavy quark expansion [PDF]

, 2000
We study the corrections due to renormalons to the heavy hadron decay width.The renormalons contribution estimated in terms of finite gluon mass based on the assumption that the gluon mass represents the short distance nonperturbative effects in the ...

A self-consistent framework of topological amplitude and its SU(N) decomposition

Journal of High Energy Physics, 2021
We propose a systematic theoretical framework for the topological amplitudes of the heavy meson decays and their SU(N) decomposition. In the framework, the topologies are expressed in invariant tensors and classified into tree- and penguin-operator ...

Semileptonic B Decays from an NRQCD/D234 Action [PDF]

, 2002
Semileptonic B decays are studied on quenched anisotropic lattices using Symanzik improved glue, NRQCD heavy quark and D234 light quark actions. We employ constrained fits to extract ground state contributions to two- and three-point correlators. Results

STAR highlights on heavy ion physics

EPJ Web of Conferences, 2015
RHIC-STAR is a mid-rapidity collider experiment for studying high energy nuclear collisions. The main physics goals of STAR experiment are 1) studying the properties of the strongly coupled Quark Gluon Plasma 2) explore the QCD phase diagram structure ...

Apparent unitarity violation in high mass region of MbW from a “hidden” top partner at high energy colliders

Physics Letters B, 2016
Perturbative unitarity conditions have been playing an important role in estimating the energy scale of new physics, including the Higgs mass as the most important example.

From topological amplitude to rescattering dynamics

Journal of High Energy Physics, 2022
We proposed a theoretical framework to correlate the topological diagram at quark level and rescattering dynamics at hadron level. In the framework, both the hadronic triangle diagram, and the topological-scattering diagram, which is the intermediate ...

Charm and beauty of the Large Hadron Collider [PDF]

, 2005
With the acceleration of lead nuclei in the LHC, heavy-ion physics will enter a new energy domain. One of the main novelties introduced by the 30-fold energy-jump from RHIC to the LHC is the abundant heavy-quark production.

The static hard-loop gluon propagator to all orders in anisotropy

Journal of High Energy Physics, 2017
We calculate the (semi-)static hard-loop self-energy and propagator using the Keldysh formalism in a momentum-space anisotropic quark-gluon plasma. The static retarded, advanced, and Feynman (symmetric) self-energies and propagators are calculated to all
