## Latest Announcements

• Weather update: daytime highs in the 68-75 F range (20 - 24 Celcius); nighttime lows around 50 F (10 Celsius). No rain forecast for the next week.
• Thanks to last-minute cancellations we have been able to accommodate several people from the waiting list. The agenda reflecting the latest changes is here. Please let us know if you would like to update your talk title.
• Here is the most recent list of registered participants. The workshop remains AT CAPACITY: the talk schedule and our guest house block are full. Please check that the dates we have for you are accurate.
• Notice that the list of participants has two groups, depending on how the reservation was made. If your name is in the first group (courtesy hold with credit cards), be advised that cancellations with less than a 24-hour notice will incur penalties from the guest house. If you need to adjust your reservation please call them promptly. Please be sure to also inform us of any changes made with the guest house.
• For the participants in the second group: you reservation was guaranteed by us and the guest house will charge us stiff penalties for any no-shows or shortened stays. Inform us at once of any emergency circumstances that may require you to make changes.
• 34 people have registered for the workshop dinner on Tuesday, March 14. The venue is Trellis Restaurant. Those who have initially paid $70 for this event should have$20 credited back to their credit cards.
• Attention all non-US citizens: please remember to bring your valid original passport and applicable visa with any supporting immigration documentation. You will need to take them to the International Services Office during your stay at SLAC. See here for more information.
• Overseas speakers: please ensure that you get either a B-1 or a WB ("Business") stamps upon entry (depending on the country you are coming from). Please show your invitation letter and a printout of the PINS website to the CBP officer. Individuals with a "Tourist" status (WT or B-2) are prohibited from speaking at conferences/seminars held at SLAC or receiving travel support (guest house stay). If there is a concern at customs, the person should politely escalate to a supervisor. See here (SLAC) and here (US Dept. of State) for more information.
• All speakers: you are allowed and in fact encouraged to use your own laptops. The projector will be connected via a standard VGA port. Please remember to bring any necessary adapters and other accessories you'd like to use (remotes for changing slides, etc). There will be a SLAC laptop as a backup option, in case something goes wrong.
• Please have a PDF version of your talk ready for posting on this website. Past experience shows that it is very important to do this in real time, to promote discussions.

## Synopsis

Neutrino physics has seen remarkable progress since the first discovery of flavor oscillations. We are now measuring flavor transformations with unprecedented precision, using ultra-high-energy neutrinos to probe distant objects in the universe, and testing neutrino imprints on the CMB and cosmic structure. On the drawing board are next-generation experiments that will measure subtle effects of CP-violation, search for additional neutrino states, and look in the core of the next galactic supernova. With every year bringing new breakthroughs, it is timely to reassess where we stand and what urgent questions need to be addressed to ensure the success of the future experiments. The workshop will cover many facets of modern neutrino physics, from experimental updates, to open questions in neutrino theory, to astrophysical and cosmological neutrinos.

We encourage participants to stay for the entire week. However, if you must limit your stay here -- we all have teaching duties, committees, etc -- please let us know your exact dates so that your talk is scheduled, and accommodations booked, accordingly. In planning your attendance, keep in mind the schedule: generally, experimental talks are concentrated in the beginning of the week, models in the middle and astrophysics and cosmology are covered in the second half.

## Topics to be covered

• Latest precision measurements of the oscillation parameters
• Models of the neutrino sector
• Searches for new physics beyond the three-flavor paradigm
• Neutrino-nuleon and neutrino-nucleus scattering cross sections
• Supernova neutrinos
• Ultra-high energy astrophysical neutrinos
• Cosmological signatures of neutrinos

## Venue

The workshop will be held on site at  SLAC, in the Redwood conference room, on the first floor of the ROB building (Bldg. 48, see the B30 square in this map). The Stanford guest house is also located at SLAC (C33 square of the map). Here is the location of SLAC on Google Maps

The list of participants can be found here. All external participants are required to pay a registration fee of $180 to confirm their attendance. The guest house will release the room if the registration fee is not received. SLAC participants should register with STAP funds. Please select the appropriate menu option on the registration page. ## Speaker Instructions By default, talks are scheduled to be 45 minutes long. Experience shows that this format is generally superior to 15-20 minute talks that are common at most large conferences these days. Invited experimental presentations are allocated 60 minutes, to allow the full exposition of the experimental program (e.g., oscillation measurements and cross section results). A limited number of theory speakers have been asked to give overviews of specific topics. In such cases, rather than talking about own work, one is expected to include an introduction to the subject, a survey of the literature, a list of outstanding problems, etc. The corresponding slots are also one hour long. You can most certainly request a shorter time slot: this will in fact help lighten up what is presently a very full schedule. As for getting more time for your talk, this may be tricky to accommodate, but if you have a compelling case please email us and we will do what we can (this involves working with the other speakers in your session). Finally, we will collect the PDF files of all talks, for posting on this web site more or less in real time. Experience from the past years shows that immediate availability of slides promotes better understanding and discussions and is particularly helpful for students and postdocs learning the subject. ## Getting Here SLAC and Stanford University are located in the heart of Northern California's Silicon Valley. The closest airports are San Francisco International (SFO) and San Jose International (SJC), with flying into Oakland (OAK) across the San Francisco Bay also a possibility. The Supershuttle can take you from SFO to SLAC for$25 (shared-ride van) or \$77 (non-stop van) one-way. Indicate "Stanford Guesthouse" as your destination when making a reservation on their website. Numerous other options exist, including Uber or Lyft.

The SLAC website provides helpful driving directions and SLAC visitor maps.

## Historical Note

This workshop is a direct decendant of the INFO (Implications of Neutrino Flavor Oscillations) series of meetings that were held bi-annually in Santa Fe, New Mexico from 2005 to 2015. The agendas for those meetings, and the PDFs of all talks, are still available: INFO 05, INFO 07, INFO 09, INFO 11, INFO 13, INFO 15. For PINS, we aim to follow the same format and philosophy: presentations on both theory and experiment, topics in particle and nuclear physics as well as in neutrino astrophysics, no parallel sessions, no 15-20 minute talks, ample time for discussion.
