Working Document for the creation of a Doctorate in Archaeoastronomy and Astrophysics in the UNSAAC of Cusco Working Document for the creation of a Doctorate in Archaeoastronomy and Astrophysics in the UNSAAC of Cusco Introduction The First International Congress on Astrophysics and Archeology of the UNSAAC was held on the Auditorium of the Faculty of Science on July 4, 5 and 6, 2019 with the presence of local professors, foreign guests, students and university authorities with the programming in annex . The objective of this event was to discuss and shape a proposal for the creation of a Postgraduate degree in Archaeoastronomy and Astrophysics at the Doctorate level, giving a strong boost to human resources research and training activities at UNSAAC. The initiative of the meeting had the contribution of several teachers of the institution, from the first contacts made by the meeting coordinator (CZV) with Professor Milton Rojas Gamarra, in Ollantaytambo, in 2018, during the IWARA2018 meeting (8th International Workshop on Astronomy and Relativistic Astrophysics), until the later stages that culminated with the writing of this proposal. Among the various professors involved in the different stages of the meeting, we highlight the relevant participation of professors Marco Antonio Zamalloa Jara, Milton Rojas Gamarra, Miriam H. Romero Peña, Pastor Raúl Chura Serrano, Sayri Tupac García Roca and Victor Ayma. We also cite the extremely important contribution of the UNSAAC authorities.

Muon Spallation in Double Chooz
Muon Spallation in Double Chooz Claire Thomas∗ REU, Columbia University and MIT (Dated: August 10, 2009) This report presents my work for Double Chooz at MIT during the 2009 Summer REU program, funded by Columbia University. Double Chooz is a reactor neutrino experiment that aims to measure the mixing parameter θ13. The experiment detects electron antineutrinos via inverse beta decay. Neutrons and light nuclei made in muon spallation are a major background to the experiment. The delayed neutron emitter 9Li is especially problematic because it mimics the inverse beta decay signal. For this reason I studied muon spallation in Double Chooz, focusing on the production and subsequent decay of 9Li. There are two key differences between 9Li decay and inverse beta decay. The first is that 9Li is a β− decay, so it emits an electron, whereas inverse beta decay emits a positron. The second difference is the energy of the neutrons emitted. In 9Li decay the neutron energy is on the order of MeV, whereas the inverse beta decay neutron has a negligible kinetic energy. Since Double Chooz does not distinguish charge, the positrons and electrons are not easy to distinguish. First, I ran simulations of electrons and positrons in the Double Chooz detector and constructed a late light variable to distinguish them from electrons. This proved insufficient, so I wrote general software to simulate radioactive decays in the Double Chooz detector. In this report I present the deposited energy spectra of a few important decays. 1.

Neutrino Oscillation Studies with Reactors
REVIEW Received 3 Nov 2014 | Accepted 17 Mar 2015 | Published 27 Apr 2015 DOI: 10.1038/ncomms7935 OPEN Neutrino oscillation studies with reactors P. Vogel1, L.J. Wen2 & C. Zhang3 Nuclear reactors are one of the most intense, pure, controllable, cost-effective and well- understood sources of neutrinos. Reactors have played a major role in the study of neutrino oscillations, a phenomenon that indicates that neutrinos have mass and that neutrino flavours are quantum mechanical mixtures. Over the past several decades, reactors were used in the discovery of neutrinos, were crucial in solving the solar neutrino puzzle, and allowed the determination of the smallest mixing angle y13. In the near future, reactors will help to determine the neutrino mass hierarchy and to solve the puzzling issue of sterile neutrinos. eutrinos, the products of radioactive decay among other things, are somewhat enigmatic, since they can travel enormous distances through matter without interacting even once. NUnderstanding their properties in detail is fundamentally important. Notwithstanding that they are so very difficult to observe, great progress in this field has been achieved in recent decades. The study of neutrinos is opening a path for the generalization of the so-called Standard Model that explains most of what we know about elementary particles and their interactions, but in the view of most physicists is incomplete. The Standard Model of electroweak interactions, developed in late 1960s, incorporates À À neutrinos (ne, nm, nt) as left-handed partners of the three families of charged leptons (e , m , t À ). Since weak interactions are the only way neutrinos interact with anything, the un-needed right-handed components of the neutrino field are absent in the Model by definition and neutrinos are assumed to be massless, with the individual lepton number (that is, the number of leptons of a given flavour or family) being strictly conserved.
