First event-by-event fluctuation studies in Pb-Pb collisions at LHC energy by the ALICE experiment
The presence of the phase transition can manifest itself by the
characteristic behavior of several observables which may vary dramatically from
one event to the other. Thus, the study of various conserved quantities on an
event-by-event basis offers the possibility to study the phase transition and
the nature of high density matter. The ALICE experiment is well suited for
precise event-by-event measurements of various quantities. In this article, the
event-by-event fluctuations of mean transverse momentum and net-charge
distributions as measured by the ALICE experiment are presented
Model comparison of the transverse momentum spectra of charged hadrons produced in collision at TeV
Transverse Momentum, , spectra is of prime importance in order to
extract crucial information about the evolution dynamics of the system of
particles produced in the collider experiments. In this work, the transverse
momentum spectra of charged hadrons produced in collision at TeV
has been analyzed using different distribution functions in order to gain
strong insight into the information that can be extracted from the spectra. We
have also discussed the applicability of Pearson distribution on the spectra of
charged hadron at TeV
Analysing the Transverse momentum spectra at large using Pearson statistical framework
Thermodynamical description of the system created during high energy
collision requires a proper thermodynamical framework to study the distribution
of particles. In this work, we have attempted to explain the transverse
momentum spectra of charged hadrons formed in collision at different
energies using the Pearson statistical framework. This formalism has been
proved to nicely explain the spectra of particles produced in soft processes as
well hard scattering processes in a consistent manner. For this analysis, we
have used the highest available range of published by experiments to
verify the applicability of Pearson statistical framework at large
A rare case of broad ligament pregnancy diagnosed at 36 weeks of gestation incidentally during laparotomy
Pregnancy in the broad ligament is a rare form of ectopic abdominal pregnancy with a high risk of maternal mortality. Ultrasound examination may help in the early diagnosis but mostly the diagnosis is established during surgery. We are reporting a case of broad ligament pregnancy diagnosed incidentally during laparotomy. She had uneventful postoperative recovery.
A generalized thermodynamical approach to transverse momentum spectra in high energy collision
Analysis of transverse momentum distributions is a useful tool to understand
the dynamics of relativistic particles produced in high energy collision.
Finding an accurate distribution function to approximate the spectra is a
vastly developing area of research in particle physics. In this work, we have
provided a detailed theoretical description of the application of the Pearson
statistical framework in high energy physics proposed for the first time in Ref
[6]. Here, the transverse momentum spectra of pions measured by experiments at
RHIC and LHC are also investigated in the framework of relativistic statistical
thermodynamics using Pearson distribution
