In a novel investigation into the physics of a strongly coupled quark gluon plasma, we compute for the first time the suppression of $\Upsilon$(1S) in a strongly coupled QGP and compare the results to those from a weakly coupled QGP. The complex binding energies which inform the thermal width and hence the $R_{AA}$ of the bottomonia in $\sqrt{s}_{NN}=2.76$ TeV Pb+Pb collisions are determined...
Heavy flavours (charm and beauty) quarks are produced in the early stages of ultra-relativistic collisions via hard scatterings and are an important tool for studying different aspects of Quantum Chromodynamics (QCD) in hadronic collisions. Charged-particle multiplicity gives information on the global characteristics of the event and can be exploited to investigate the possible influence of...
The measurements of heavy-flavour production via leptonic decays in proton-
proton (pp) collisions with ALICE at Large Hadron Collider (LHC) energies are
described. Heavy flavour (charm and beauty) are produced at an early stage of
the collision via hard scatterings. In ALICE, heavy-flavour measurements are
measured in the central barrel (|η|<0.9) via the semi-electronic decay channel
and at...
In heavy ion collisions, strangeness enhancement had been proposed as a
signature of the QGP formation. Surprisingly, more recent observations have
shown an enhanced production of (multi-)strange hadrons in high-multiplicity pp
and p-Pb collisions at the LHC. The multiplicity dependence of strangeness
production measured with the ALICE experiment will be discussed in pp, p-Pb,
Xe-Xe and Pb-Pb...
Based on a number of features from proton-proton collisions with Run 1 data a boson with a mass around the EW scale was postulated such that a significant fraction of its decays would entail the Standard Model (SM) Higgs boson and an additional scalar, $S$. One of the phenomenological implications of a simplified model, where $S$ is treated a SM Higgs boson, is the the anomalous production of...
In this talk we discuss a model consisting of Two-Higgs Doublet Model (2HDM) along with a CP even scalar singlet with different global ${\mathbb Z}_2$ symmetry. Let us call this new model "2HDM+S". We discuss the constraints on its parameters emanating from our phenomenological studies. We use it further to explain the possibility of producing new scalars in the electron-proton collider...
The muon anomalous magnetic moment (muon $𝑔−2$) is among the most precisely measured quantities in particle physics. The latest measurement is discrepant from the predictions of the Standard Model – the difference between the experimental and theoretical values is in the range of three to four standard deviations. One possible explanation for this is the interaction of the muon with particles...
