30th Annual Meeting of the Division of Particles and Fields (DPyC) of the Mexican Physical Society & XV Mexican Workshop on Particles and Fields (MWPF)

The 30th Annual Meeting of the Division of Particles and Fields (DPyC) of the Mexican Physical Society was held at Edificio Carolino, Benemérita Universidad Autónoma de Puebla, Mexico, on 23-25 May 2016. 125 participants and 83 presentations (20 posters and 63 talks including 47 contributed, 15 invited and a closing round table discussion) of high scientific quality certify the success of this meeting and witness the good health of the DPyC. Excited and encouraged by this fact, we decided to coordinate the edition of a proceedings volume commemorating and celebrating this anniversary, including the communications corresponding to this meeting as well as those of the recent XV Mexican Workshop on Particles and Fields, held at Playa Mazatlán Beach Hotel, Mazatlán, Mexico on 2-6 November 2015, where 46 works were discussed. All presenters of these meetings were invited to contribute and the majority of them accepted -in spite of many other pressing simultaneous commitments. Additionally, we decided to invite researchers who were not able to attend these conferences, despite they used to be very involved in the activities of our community. With these invitations we also tried to reduce the inequality between male and female contributors and to enable researchers from the most isolated places in Mexico to participate, as well. Given the commemorative nature of this volume, we wished to have some historical perspec-tives on speci_c aspects of our community which were not addressed in previous texts on the birth of the DPyC [1, 2, 3, 4]. We acknowledged our colleagues preparing essays on the creation of research networks and their interactions with DPyC, on the development of accelerator physics in Mexico and on the experimental and theoretical-research summers on high-energy physics, giving our best undergrads the support to spend a summer in a world-leading institution making their _rst steps in research. The scienti_c program of the 2015Workshop and 2016 Meeting covered a wide range of topics, including physics beyond the Standard Model (theory and experimental searches, astroparticles, cosmology, dark matter and dark energy, strings and QFT fundamentals), hadronic matter (per-turbative QCD, jets and di_ractive physics, hadronic structure, soft QCD, spectroscopy, heavy ion collisions and soft physics at hadron colliders and lattice simulations), avor physics (quark masses and mixing, electroweak symmetry breaking, heavy quark physics, neutrino physics, CP viol
