Second Plenary Workshop of the Muon g-2 Theory Initiative

18 June 2018 - 22 June 2018

In the coming years, experiments at Fermilab and at J-PARC plan to reduce the uncertainties on the already very precisely measured anomalous magnetic moment of the muon by a factor of four. The goal is to resolve the current tantalizing tension between theory and experiment of three to four standard deviations. On the theory side the hadronic corrections to the anomalous magnetic moment are the dominant sources of uncertainty. They must be determined with better precision in order to unambiguously discover whether or not new physics effects contribute to this quantity.

There are a number of complementary theoretical efforts underway to better understand and quantify the hadronic corrections, including dispersive methods, lattice QCD, effective field theories, and QCD models. The Muon (g-2) Theory Initiative was formed in order to facilitate interactions between the different groups through organizing a series of workshops. The goal of this workshop is to bring together theorists from the different communities to discuss, assess, and compare the status of the various efforts, and to map out strategies for obtaining the best theoretical predictions for these hadronic corrections in advance of the experimental results.

Travel and Transportation
Arrival by plane
Frankfurt Airport (FRA)

Frankfurt Airport is served by more than 1,000 flights each day to and from nearly 300 destinations in over 100 countries. It is well connected to Mainz by a local train service.

To take a train to Mainz, follow the signs “Regionalbahnhof / local trains” at the airport to get to the regional train station. Tickets must be purchased prior to boarding the trains at the ticket vending machines in the train station. Please note that the machines only accept coins, banknotes of up to 20€, or European bank cards according to the Maestro and v-pay standards. The correct ticket is called “Einzelfahrkarte nach 6500” (Mainz/Wiesbaden) and costs 4.90€ per person.

The local train “S8” to “Mainz Hauptbahnhof” (Mainz Main Station), which departs every 30 minutes during the day, is the easiest option. Alternatively, you may take any regional train (“Regionalbahn”/RB or “Regionalexpress”/RE) stopping at Mainz Hauptbahnhof.

Hahn Airport (HHN)

Frankfurt-Hahn Airport is served by European budget airlines Ryanair, Wizz Air and SunExpress. There is a non-stop coach service “Bus Route 600” to Mainz Main Station (bus stop “N”) leaving from the airport coach station (“Busbahnhof”). To get to the coach station, turn right when leaving the terminal and walk past the parking lot. The coach fare is 13.50€. Tickets can be pre-ordered on-line or bought directly from the driver.

Arrival by railway

The German railway network (“Deutsche Bahn”) provides a very comfortable, cost- effective and environmentally conscious way to travel. There are direct long-distance trains (EC, ICE, IC) to Mainz from many cities in Germany. From other starting points, one may have to change trains in Frankfurt Main Station (“Frankfurt Hauptbahnhof”), Frankfurt Airport (“Frankfurt Flughafen Fernbahnhof”) or at Mannheim. Tickets can be purchased on-line via the web services of Deutsche Bahn or from ticket vending machines at the station.

Local transportation

From Mainz Hauptbahnhof, the easiest way to get to the conference venue is to use the “Mainzelbahn”: tram lines 51 (direction “Lerchenberg/Hindemithstraße”), 53 (direction “Lerchenberg/Hindemithstraße”) or 59 (direction “Bretzenheim/Hochschule Mainz”) stop at “Friedrich-von-Pfeiffer-Weg”, from where you can easily walk to the Helmholtz Institute building.

Conference Dinner

The conference dinner, which is kindly sponsored by NEC, will take place in the beergarden of the Favorite Parkhotel on Wednesday at 19:00.

To get to the dinner venue, take either the bus 62 (direction "Weisenau") or the bus 63 (direction "Laubenheim") and exit at the stop "Rosengarten", or take the bus 60 (direction "Ginsheim") or the bus 61 (direction "Laubenheim") and exit at the stop "An der Favorite".
