The Compressed Baryonic Matter (CBM) experiment at FAIR will investigate the QCD phase diagram at high net-baryon density ($\mu_{B} > 400\ \textrm{Me}V$) in the energy range of $\sqrt{s_{NN}} = 2.9−4.9\ \textrm{Ge}V$. Precise determination of dense baryonic matter properties requires multi-differential measurements of strange hadron yields, both for most copiously produced kaons and $\Lambda$...

Measurement of non-prompt $\Lambda_c^+$ production in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE
Daniel Battistini for the ALICE Collaboration
In proton-proton (pp) collisions, the production of HF hadrons is typically described as a convolution of the parton distribution functions of the colliding protons, the partonic cross section, and the Fragmentation Functions (FFs). The...

The origin of possible collective phenomena in pp collisions with high final-state multiplicity still remains an open question. Recent theories explain the presence of collectivity with cold QCD effects. These can be studied in experiments by categorizing the events with transverse activity classifier $R_{\rm T}$, which is correlated to the intensity of these QCD effects. The ALICE detector...

Heavy-flavour quarks (charm and beauty) are produced on a very short time scale in initial hard-scattering processes. They experience the entire evolution of the ultrarelativistic-collision which makes them excellent probes for the characterization of the quark-gluon plasma (QGP) formed in heavy-ion collisions.
In particular, the comparison between beauty and charm measurements is a crucial...

In this contribution, the performance of a beauty-jet tagging algorithm based on transverse impact-parameter threshold cuts will be discussed for data collected by the ALICE experiment in proton-proton collisions at $\sqrt{s}=13\,$TeV. Owing to the relatively large lifetimes and the cascade of weak decays of beauty hadrons, the measurement of the impact parameter of tracks within jets can be...

Heavy quarks, due to their large external masses, are produced predominantly through initial hard scatterings involving gluons in high energy ion-ion and electron-ion collisions. This makes them unique probes to study QCD emergent properties of the hot QGP as well as of the cold nuclear medium. Measurements of heavy quark hadron production also offer new insights into the hadronization...

J/$\psi$ is an important probe to the properties of the quark-gluon plasma (QGP) created in heavy-ion collisions. Measurements from SPS, RHIC, and the LHC experiments show that J/$\psi$ production in heavy-ion collisions is an interplay of several effects, including dissociation and regeneration in QGP and cold nuclear matter effects. Studying the properties of the QGP via J/$\psi$ requires a...

Measurements of hard probes such as jets and heavy flavor hadrons are essential to study the microscopic properties of the Quark-Gluon Plasma. In particular, due to their large intrinsic mass, measurements involving heavy flavor quarks are important to understand the mass dependence of the parton energy loss. With the Heavy Flavor Tracker at STAR, the opportunity to use fully reconstructed $D$...

Strangeness production has been suggested as a sensitive probe to the early-time dynamics of the nuclear matter created in heavy-ion collisions. Transverse momentum distributions and yields of strange hadrons and resonances provide important information about the particle production mechanisms and help us to understand the properties of the created medium and its evolution in these collisions....

Quarkonium production is one of the essential probes for studying the properties of the quark-gluon plasma (QGP) created in relativistic heavy-ion collisions. The suppression of J$/\psi$ meson due to colour screening in medium and medium-induced dissociation was initially proposed as direct evidence of QGP formation. The non-prompt component of J$/\psi$ production from b-hadron decays...

The strong electromagnetic field generated by the colliding nuclei in heavy-ion collisions can be represented by a spectrum of equivalent photons, leading to photon-induced interactions. Significant enhancements of the J/$\psi$ production via $e^{+}e^{-}$ decay channel at very low transverse momentum ($p_{T}$) have been observed by the STAR and ALICE collaborations in peripheral heavy-ion...

We compute the production of J/ψ mesons in different rapidity bins as a function of event activity in p+p and p+Pb collisions at LHC energies within the color glass condensate framework combined with non-relativistic QCD (NRQCD) or an Improved Color Evaporation model (ICEM) to describe the J/ψ hadronization. We demonstrate that deviations from a linear increase of J/ψ multiplicity with...

Heavy-quark production in nuclear collisions is an important tool to access the properties and evolution of deconfined matter. Corresponding studies on pp collisions serve as a reference process, as well as a test of various aspects of QCD. A detection technique that was little explored until now at LHC energy is the analysis of the high-mass region of the dilepton invariant mass spectrum...
