The elastic, inelastic, and transfer cross sections are measured for the ${}^{6}\mathrm{Li}+{}^{209}\mathrm{Bi}$ reaction at energies around Coulomb barrier. optical model analysis of elastic scattering shows a breakup threshold anomaly in energy dependence real imaginary potentials. observed is found to be consistent with dynamic polarization potential obtained from coupled-channels calculations that explain above channels simultaneously. A comparison different probabilities reveals...
We make a systematic study of transverse momentum (pT) spectra hadrons produced in p + and different centralities Au+Au collisions at center mass energy 200 GeV using phenomenological fit functions. The Tsallis distribution gives very good description hadron with just two parameters but does not produce the same intermediate pT. To explain heavy ion wider pT range we propose modified function by introducing an additional parameter that accounts for collective flow. new analytical both mesons...
A fair knowledge of the atmospheric muon distributions at Earth is a prerequisite for simulations cosmic ray setups and rare event search detectors. modified power law proposed energy distribution which gives good description data in low as well high regime. Using this distribution, analytical forms zenith angle [Formula: see text] are obtained. Assuming flat Earth, it leads to form where shown that parameter nothing but distribution. Exact function obtained inclined trajectory muon. new...

Measurements of elastic scattering for the $^{6}\mathrm{Li}+^{90}\mathrm{Zr}$ system has been performed at various energies, namely, 11, 12, 13, 15, 17, 19, 21, 25, and 30 MeV, to study energy dependence interaction potential. Angular distributions have measured in a wide angular range extract behavior potential reliably.

We have studied the reaction $p+$$^{27}\mathrm{Al}$ $\ensuremath{\rightarrow}$ $^{3}\mathrm{He}$$+p+{\ensuremath{\pi}}^{\ensuremath{-}}+X$ at recoil-free kinematics. An $\ensuremath{\eta}$ meson possibly produced in this would be thus almost rest laboratory system and could therefore bound with high probability, if nuclear states exist. The decay of such a state through ${N}^{*}(1535)$ resonance lead to proton-${\ensuremath{\pi}}^{\ensuremath{-}}$ pair emitted opposite directions. For these...
We present the systematic analysis of transverse momentum ($p_T$) spectra identified hadrons in p+p collisions at RHIC ($\sqrt{s}$ = 62.4 and 200 GeV) LHC energies 0.9, 2.76 7.0 TeV) using phenomenological fit functions. review various forms Hagedorn Tsallis distributions show their equivalence. use distribution which successfully describes two parameters, temperature $T$ governs soft bulk power $n$ determines initial production partonic collisions. obtain these parameters for pions, kaons...
We study the possibility of generating dark matter (DM) and baryon asymmetry Universe (BAU) simultaneously in an asymmetric DM framework, which also alleviates small-scale structure issues cold DM. While thermal relic such self-interacting remains underabundant due to efficient annihilation into light mediators, a nonzero sector can lead survival required Universe. The existence mediator leads self-interactions at small scales while keeping properties similar large scales. It ensures that...
We reexamine the Glauber model and calculate total reaction cross section as a function of energy in low intermediate range, where many corrections are effective. The most significant effect this range is by modification trajectory due to Coulomb field. nuclear field also taken into account self-consistent way. ranges which particular effective quantified, it found that when center mass system becomes 30 times barrier, none really required. sections for light heavy systems, from barrier...
Inclusive ($\mathrm{direct}+\mathrm{compound}$) $\ensuremath{\alpha}$ production for the $^{6}\mathrm{Li}+^{90}\mathrm{Zr}$ system is measured at near barrier energies, namely, $15,17,19,21,25$, and 30 MeV. The data are treated in statistical model distorted-wave Born approximation framework to disentangle degree of competition between direct compound reaction channels. A substantial contribution from channels obtained but found be dominant mechanism these energies. Estimation breakup...
The meson spectra provide insight into the particle production mechanism and interaction in hadronic quark gluon plasma (QGP) phases. detailed study of systematics is important also because it acts as ingredient for estimating decay backgrounds photon, single lepton dilepton which are penetrating probes plasma. In this work, we parameterize experimentally measured pion then obtain other light mesons using a property known $m_T$ scaling. $m_{T}$ scaled each compared with experimental data...

The bottomonium states due to their varying binding energies dissolve at different temperatures and thus nuclear modification factors relative yields have potential map the properties of Quark Gluon Plasma (QGP). We estimate suppression bottomonia color screening in an expanding QGP finite lifetime size with conditions relevant for PbPb collisions LHC. $\Upsilon$ recent results on dissociation been used as ingredient study. ratios are then obtained a function transverse momentum centrality....
We analyze the transverse momentum spectra of charged pions measured in Au + collisions at [Formula: see text] and Pb using Tsallis distribution modified to include flow. All are well described by an extended range upto 6 GeV/c. The kinetic freeze-out temperature (T), average flow (β) degree nonthermalization (q) obtained as a function system size for both energies. With increasing β shows trend whereas T remains constant. While systems RHIC LHC energies show similar q, parameter is higher...
We investigate the scenario of homogeneous nucleation for a first order quark-hadron phase transition in rapidly expanding background quark gluon plasma. Using an improved preexponential factor rate, we solve set coupled equations to study hadronization and hydrodynamical evolution matter. It is found that significant supercooling possible before begins. This also suggests spinodal decomposition competes with may provide alternative mechanism conversion particularly if strong enough medium...
