PhD position in Direct Dark Matter Search with Liquid Argon Detectors

The Dark Matter research group (CIEMAT-DM) of the CIEMAT-FP Unit (Centre for Research in Energy, Environment and Technology in Madrid, Spain) announces the upcoming opening of a predoctoral position for outstanding young MSc graduates interested in working in direct Dark Matter search activities towards a PhD Thesis. The 4-year PhD contract is funded by CIEMAT. The official call will be announced in the webpage http://www.ciemat.es/portal.do?IDM=254&NM=2 in the upcoming weeks (February-March). It will also be announced at http://cfp.ciemat.es/predoc, http://darkmatter.ciemat.es/predoc and in social networks. The candidate must have a Master Degree in Physics (according to the Bologna Declaration).
The CIEMAT-DM group participates in the DArT experiment in the Canfranc Underground Laboratory (LSC, Spain), in DEAP-3600 (SNOLAB, Canada) and in the DarkSide-20k experiment to be installed in the Gran Sasso National Laboratory (LNGS, L’Aquila, Italy). The PhD student is expected to work in the analysis of physics data, as well as in the development of innovative hardware, detector simulation and analysis software for current and future LAr detectors. The selected student is expected to spend part of his/her time at LSC, LNGS, and other collaborating institutes worldwide.

Nuevo canal de Telegram sobre física de astropartículas

La Acción COST CA18108 “Quantum gravity phenomenology in the multi-messenger approach” (QG-MM) ha inaugurado recientemente el canal de Telegram  “Quantum Gravity and Multi-Messenger Physics” como nuevo medio de divulgación con noticias de interés en cosmología, física de partículas y astropartículas y de los “mensajeros cósmicos” (rayos gamma, neutrinos, rayos cósmicos y ondas gravitacionales), así como noticias de la propia Acción, cuyo objetivo principal es reunir a físicos teóricos y experimentales para trabajar conjuntamente en la predicción y posibilidad de observación de efectos de gravedad cuántica a través de la física multi-mensajero.

En el canal de Telegram, además, se publican diariamente durante este mes de febrero reseñas biográficas de las científicas favoritas de miembros de la Acción, como conmemoración del 11-F como Día Internacional de la Mujer y la Niña en la Ciencia. El hilo puede además seguirse en Twitter.

TRISEP-2020 Summer school

TRISEP is a two-week annual summer school for graduate students and junior post-doctoral fellows held this year at SNOLAB and Laurentian University from July 6 to 17 with a tour of SNOLAB on July 5.

The topics include the standard model, neutrino physics, long-baseline oscillations, neutrinoless double beta decay, physics beyond the standard model at the LHC, dark matter, dark matter scenarios and direct detection, simulation with GEANT4, and statistics.

For details regarding the school, application, and student support please see http://www.trisep.ca/.

The TRi-Institute School in Elementary Particles is hosted annually in rotation by TRIUMF, the Perimeter Institute, and SNOLAB. We are grateful for the support of the Institute of Particle Physics and Laurentian University.

Ilya L. Shapiro, “Local and nonlocal models of quantum gravity” 🗓

The main difficulty of perturbative quantum gravity (QG) in D=4 dimensions is the conflict between renormalizability and unitarity of the theory. The simplest version of QG is based on General Relativity and turns out to be nonrenormalizable. One can construct renormalizable and even superrenormalizable versions of QG by introducing higher derivatives. In the local versions of higher derivative models of QG there are always unphysical higherderivative massive unphysical ghosts. One can construct non-polynomial in derivatives (or, equivalently, nonlocal) models of QG, which have no ghosts at the tree level. However, taking loop corrections into account one meets infinite amount of ghost-like complex states. The theories of both local and nonlocal types attracted a lot of attention in the last years and our purpose it to present a brief review of the problems and perspectives of these models, according to the present-day understanding.
