Investigating initial state of heavy-ion collisions using $[p_{\text{T}}]$ fluctuations and $v_n-[p_{\text{T}}]$ correlations in ATLAS
/ Bold, Tomasz (UC, Irvine (main) ; CERN)
/ATLAS Collaboration
This proceeding presents recent studies of event-wise mean transverse momentum, $[p_{\text{T}}]$ that can help differentiate the interplay between the effect of radial collectivity, random thermal motion and deformation in nuclear geometry. In addition, the Pearson Correlation Coefficient (PCC) between flow, $v_n$ and $[p_{\text{T}}]$, $\rho(v_n,[p_{\text{T}}])$, will be shown. [...]

Alpha emission from fast neutron interactions with $^{64}$Zn nuclei
/ Oprea, Cristiana (Unlisted, CH) ; Mihul, Alexandru (Bucharest U. ; CERN) ; Oprea, Ioan (Unlisted, CH) ; Gruia, Ion (Bucharest U. ; Unlisted, CH) ; Zgura, Sorin (Unlisted, CH)
In this study, the nuclear process 64Zn(n, α)61Ni induced by fast neutrons in the 64Zn nucleus was investigated. With the authors' computer programs and Talys codes, cross-sections, angular correlations, and forward-backward asymmetry effects were investigated for incident neutrons with energies ranging from 0.5 MeV to 25 MeV.

Pulsed Production of Antihydrogen in AEgIS
/ AEgIS Collaboration
Low-temperature antihydrogen atoms are an effective tool to probe the validity of the fundamental laws of Physics, for example the Weak Equivalence Principle (WEP) for antimatter, and -generally speaking- it is obvious that colder atoms will increase the level of precision.After the first production of cold antihydrogen in 2002 [1], experimental efforts have substantially progressed, with really competitive results already reached by adapting to cold antiatoms some well-known techniques pre- viously developed for ordinary atoms. Unfortunately, the number of antihydrogen atoms that can be produced in dedicated experiments is many orders of magnitude smaller than of hydrogen atoms, so the development of novel techniques to enhance the production of antihydrogen with well defined (and possibly controlled) conditions is essential to improve the sensitivity.We present here some experimental results achieved by the AEgIS Collaboration, based at the CERN AD (Antiproton Decelerator) on the production of antihydrogen in a pulsed mode where the production time of 90% of atoms is known with an uncertainty of ~ 250 ns [2].

From the Hadronic String to Quantum Gravity ... and Back
/ Veneziano, Gabriele (CERN ; College de France)
I will outline the conceptual developments that led, through half a century, to the present formulation of string theory. The phenomenological observation of Dolen-Horn-Schmit “duality” in 1967, the formulation, a year later, of the Dual Resonance Model, and its eventual interpretation as a theory of quantum relativistic strings, marked the birth of the hadronic string. [...]

A precise understanding of hadronic interactions is essential to interpreting the mass composition of ultra-high energy cosmic rays from the results of air shower experiments. The Large Hadron Collier forward (LHCf) experiment aims to measure forward neutral particles for validation of hadronic interaction models adopted in air shower simulations. [...]
