Production of W-bosons in p-Pb collisions measured with ALICE at the LHC

W bosons are produced in hard scattering processes of partons in collisions of hadrons and they do not interact strongly with the medium produced in high-energy heavy-ion collisions. Therefore, in p-Pb collisions the measurement of W-boson yields represents a standard candle to check the validity of binary-collision scaling and can provide important constraints on the parton distribution functions, which can be modified in nuclei with respect to protons or neutrons. At the LHC, ALICE (A Large Ion Collider Experiment) is dedicated to the study of ultrarelativistic heavy-ion collisions, in which a hot and dense strongly-interacting medium is formed. At forward rapidities ALICE is equipped with a muon spectrometer that allows measurements of dimuon decays of quarkonia, muons from heavy-flavour hadron decays and also W bosons via their single-muon decay. In ALICE W-boson cross sections were measured in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV via the contribution of their muonic decays to the inclusive $p_\mathrm{T}$-differential muon yield measured at forward (2.03 < $y_{cms}$ < 3.53) and backward rapidity (-4.46 < $y_{cms}$ < -2.96) in various event-activity intervals. Recent results obtained from these measurements will be presented and the measured cross sections will be compared to perturbative Quantum Chromodynamics calculations at next-to-leading order.Comment: Proceedings of Science,XXIII International Workshop on Deep-Inelastic Scattering,Dallas, Texas 27 April - 1 May 201

Exploring the role of women in development in the case of Sweetwater, uMgungundlovu District in KwaZulu-Natal.

Masters. University of KwaZulu-Natal, Durban.The study intends to survey the difficulties that are influencing the local area of Sweetwater with respect to development. The study’s primary focus was on ‘women in development’ by highlighting the intersection of gender and culture that gives inadvertently unequal opportunities amongst the genders. This study explored the role of women in development in the case of Sweetwater, uMgungundlovu District in KwaZulu-Natal. A desktop study was used to analyze the role of women in development. No primary data was collected for this study. Radical feminism theory was used in this study. The objectives of the study are to explore gender roles through a cultural lens in Sweetwater, uMgungundlovu; to examine the opportunities that women encounter in development in the study area; to examine the challenges that women face in development in Sweetwater, uMgungundlovu and to explore the challenges in the land tenure reform program in Sweetwater. Findings indicate that a grassroots movement is required to eliminate the inequalities and social injustice that prevail among gender. The findings show that South Africa has suffered great historical events. However, the researcher believes that despite of all the historical events, culture oppresses women and their role in development. The Msunduzi municipality advocates for a green economy. It is progressing although it still encounters challenges with addressing equality amongst gender. The inequalities affect women the most. The inequalities amongst genders deprive women of an opportunity to enhance their livelihoods. The unity in society would assist in rectifying the injustice against women that took place during the colonial and apartheid era. To promote gender equality; the traditional leaders, communities, and the government should work together to promote sustainable livelihoods to improve their position in society. Women should participate in women empowerment; there should be fair distribution of land and resources and there should be government interventions and Gender equality awareness programs

Design and development of the ALICE common readout unit user logic firmware for the Muon Identifier readout chain

A Large Ion Collider Experiment (ALICE) at the Large Hadron Collider (LHC) at CERN went through a major upgrade in which some of its subdetectors were replaced with new ones, while others are equipped with new electronics. The aim of the upgrade is to withstand higher collision rates during the third running period (Run 3), which started in 2022. As part of the upgrade, certain subdetectors such as the Muon Trigger, renamed to Muon Identifier, now operate in a continuous, triggerless readout mode, in addition to the previous triggered readout mode. Due to the increased quantity of data, typical methodologies are impossible to employ without massive efforts to expand the processing capacity. Since the new ALICE computing system cannot keep up with the increased data flow of the Muon Identifier, a new processing algorithm has been established. These proceedings provide a insight to the new approach of processing the Muon Identifier readout data based on a customized user logic FPGA firmware

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe
