Analytic decay width of the Higgs boson to massive bottom quarks at next-to-next-to-leading order in QCD
The Higgs boson decay to a massive bottom quark pair provides the dominant contribution to the Higgs boson width. We present an exact result for such...

Quarks
Gell-Mann schlug 1964 vor, die Hadronen als zusammengesetzt aus Objekten mit drittelzahliger Ladung zu betrachten. Diese „Quarks“ trugen auch die...

Heavy Quarks on the Lattice
I review the basic ideas behind lattice QCD calculations that involve charm and bottom quarks. I report on the progress in getting the correct...

Photo- and electro-production of narrow exotic states: From light quarks to charm and up to bottom
Accessing a full image of the inner content of hadrons represents a central endeavour of modern particle physics, with the main scientific motivation...

Transverse momentum distributions of heavy hadrons and polarized heavy quarks
We initiate the study of transverse momentum-dependent (TMD) fragmentation functions for heavy quarks, demonstrate their factorization in terms of...

Exploring the flavor structure of quarks and leptons with reinforcement learning
We propose a method to explore the flavor structure of quarks and leptons with reinforcement learning. As a concrete model, we utilize a basic...

Heavy vector-like quarks decaying to exotic scalars: a case study with triplets
We investigate the pair production of a vector-like quark triplet with hypercharge 5/3 decaying into top quark and a complex scalar triplet with...

Secondary massive quarks with the Mellin-Barnes expansion
Processes involving only massless or massive quarks at tree-level get corrections from massive (lighter, heavier, or equal-mass) secondary quarks...

Global constraints on non-standard neutrino interactions with quarks and electrons
We derive new constraints on effective four-fermion neutrino non-standard interactions with both quarks and electrons. This is done through the...

Magnetic catalysis in holographic model with two types of anisotropy for heavy quarks
In our previous paper (Aref’eva et al. in JHEP 07:161, 2021, ar**v:2011.07023 [hep-th]) we have constructed a twice anisotropic five-dimensional...

Hadrons from Quarks and Chiral Symmetry
Chiral symmetry with its spontaneous breaking is one of the greatest achievements and has provided the basis of theoretical methods in various fields...

Quark Nuclear Physics with Heavy Quarks
Heavy quarks have been instrumental for progress in our exploration of strong interactions. Quarkonium in particular, a heavy quark-antiquark...

Empirical determination of the energy loss of heavy quarks in nuclear collisions at RHIC and LHC energies
Heavy quarks produced in the heavy ion collisions loose energy while propagting in the hot partonic matter which finally fragment to heavy ( D or B )...

Holographic model for light quarks in anisotropic hot dense QGP with external magnetic field
We present a five-dimensional twice anisotropic holographic model supported by Einstein-dilaton-three-Maxwell action describing light quarks. The...

Search for resonant production of dark quarks in the dijet final state with the ATLAS detector
This paper presents a search for a new Z ′ resonance decaying into a pair of dark quarks which hadronise into dark hadrons before promptly decaying...

Signals with six bottom quarks for charged and neutral Higgs bosons
In extensions of two Higgs doublet models with vectorlike quarks, the decays of vectorlike quarks may easily be dominated by cascade decays through...

Soft logarithms in processes with heavy quarks
Observables involving heavy quarks can be computed in perturbative QCD in two different approximation schemes: either the quark mass dependence is...

Pentaquark Production in Weak Decays of Bottom Baryons
AbstractAt present, production, properties, and decays of heavy baryons are vigorously studied both experimentally and theoretically. The

Tagging the Higgs boson decay to bottom quarks with colour-sensitive observables and the Lund jet plane
We study the problem of distinguishing b -jets stemming from the decay of a colour singlet, such as the Higgs boson, from those originating from the...
